If you run a sales team, agency, or ecommerce brand, the first quartile in Excel is more than a statistic. It is a story about who is underperforming, which campaigns are lagging, and where hidden upside might live. Q1 marks the bottom 25 percent of your data. For leads, it shows the coldest accounts. For CPC, it reveals the cheapest clicks. For revenue, it highlights the weakest products. Once you understand how to calculate Q1 with QUARTILE, QUARTILE.INC, or QUARTILE.EXC, you can segment intelligently instead of guessing.Now imagine never touching that formula again. An AI computer agent can open Excel or Google Sheets, clean your data, apply QUARTILE, pull Q1 for every market, and paste a summary into your CRM or dashboard. While it clicks, types, and checks for errors at machine speed, you stay focused on offers, creative, and strategy instead of fighting spreadsheets.
# How to Find the First Quartile in Excel and Google Sheets at ScaleYou probably do not care about quartiles for their own sake. You care because Q1 tells you which campaigns, leads, or products sit in the bottom 25% – the ones dragging the average down or quietly wasting budget. Let’s walk through practical ways to get Q1 in Excel and Google Sheets, then scale the workflow with no‑code tools and AI agents.---## 1. Manual methods in Excel and Google Sheets### 1.1 Excel QUARTILE / QUARTILE.INC / QUARTILE.EXCExcel offers several functions to get the first quartile (Q1):- QUARTILE(array, quart)- QUARTILE.INC(array, quart)- QUARTILE.EXC(array, quart)According to Microsoft: https://support.microsoft.com/en-us/office/quartile-function-93cf8f62-60cd-4fdb-8a92-8451041e1a2a**Steps (classic QUARTILE):**1. Put your numeric data in a single column, for example A2:A101.2. Click an empty cell where you want Q1, say B2.3. Enter: - `=QUARTILE(A2:A101,1)`4. Press Enter. Excel returns the first quartile (25th percentile).**Steps (recommended QUARTILE.INC / QUARTILE.EXC):**1. Use the same range A2:A101.2. In B2, type: - `=QUARTILE.INC(A2:A101,1)` to include endpoints, or - `=QUARTILE.EXC(A2:A101,1)` to exclude endpoints.3. Hit Enter. This gives a more statistically precise Q1 for many use cases.Docs:- QUARTILE.INC: https://support.microsoft.com/en-us/office/quartile-inc-function-1bbacc80-5075-42f1-aed6-47d735c4819d- QUARTILE.EXC: https://support.microsoft.com/en-us/office/quartile-exc-function-5a355b7a-840b-4a01-b0f1-f538c2864cad**Pros:** Built-in, fast, easy to audit.**Cons:** You must set up ranges and formulas each time for new datasets.### 1.2 Google Sheets QUARTILEGoogle Sheets mirrors Excel’s syntax, so your team can switch tools without relearning everything.Google’s stats function reference: https://support.google.com/docs/answer/3093991**Steps:**1. Paste your data in column A, starting at A2.2. Choose an output cell, for example B2.3. Enter: - `=QUARTILE(A2:A101,1)`4. Press Enter. Sheets returns the first quartile.You can also use QUARTILE.INC and QUARTILE.EXC in recent versions of Sheets the same way you do in Excel.**Pros:** Familiar Excel-like syntax, easy sharing and collaboration.**Cons:** Still manual; you must repeat for each new sheet or client.### 1.3 Excel Data Analysis ToolPak (descriptive stats)If you want quartiles alongside mean, median, and standard deviation, Excel’s Analysis ToolPak can generate a full descriptive summary.**Enable ToolPak (once):**1. Go to File → Options → Add-ins.2. At the bottom, choose Excel Add-ins and click Go.3. Check Analysis ToolPak → OK.**Run descriptive statistics:**1. Go to Data → Data Analysis → Descriptive Statistics.2. Set Input Range to your data (e.g., A2:A101).3. Choose an Output Range, say C2.4. Tick Summary statistics → OK.Excel outputs a stats table, including quartiles depending on version. You can cross-check Q1 from there.**Pros:** One click for a bundle of stats; good for analytics teams.**Cons:** Less flexible if you only need Q1; not reactive to new rows unless you rerun the analysis.### 1.4 Manual percentile logic (for understanding)Sometimes you want to sanity-check the formula or explain it to stakeholders.**Conceptual steps:**1. Sort your data ascending.2. Count the number of observations, n.3. Compute position p = 0.25 × (n + 1).4. If p is an integer, Q1 is the value at position p.5. If not, interpolate between the two surrounding values.You would rarely do this by hand in production, but it builds intuition for what Q1 represents.**Pros:** Builds trust and understanding.**Cons:** Way too slow and error-prone for real work.---## 2. No-code methods and automation helpersNow imagine you run weekly performance reviews across dozens of campaigns. Doing everything above by hand is a tax on your attention. No-code tools can help.### 2.1 Template-driven Sheets and Excel tablesInstead of re-creating formulas each time, create a reusable template.**In Excel:**1. Store raw data in a formatted Excel Table (Ctrl+T) named tblData.2. Add formulas referencing the table column, for example: - `=QUARTILE.INC(tblData[Revenue],1)`3. Save the workbook as a template.4. For each new campaign or client, duplicate the file and paste data into tblData. The Q1 output updates instantly.**In Google Sheets:**1. Use a dedicated Raw Data tab for imports.2. On a Metrics tab, place formulas like: - `=QUARTILE(Raw!B2:B,1)` (using an open-ended range so new rows are included).3. Save as a template and duplicate the file whenever you onboard a new client.**Pros:** Low effort, consistent structure, minimal reconfiguration.**Cons:** Still requires humans to paste or import data.### 2.2 No-code automation with Zapier, Make, or similarYou can automatically push data into Sheets or Excel and let existing formulas compute Q1.**Example: send CRM deals to Google Sheets and watch Q1 update:**1. In Google Sheets, set up a template as above with a Q1 formula on a summary tab.2. In Zapier: - Trigger: “New deal” in your CRM (e.g., HubSpot, Pipedrive). - Action: “Create Spreadsheet Row” in Google Sheets, targeting Raw Data.3. Each new row instantly affects the QUARTILE formula, so Q1 is always live.**Example: Slack alert when Q1 drops below a threshold:**1. In Sheets, calculate Q1 into a single cell, say Summary!B2.2. In Zapier or Make: - Trigger: Schedule every morning. - Action 1: “Lookup Spreadsheet Row” or “Get cell value” for Summary!B2. - Action 2: If Q1 < target, send a Slack or email alert with the value.**Pros:** No code, no manual copy-paste, near real-time Q1 visibility.**Cons:** External tools add cost and moving parts; logic still scattered between automations and spreadsheets.### 2.3 Macros and Apps Script (light low-code)If your team is comfortable recording actions, you can wrap repetitive steps in a macro.**Excel macro idea:**1. Start recording a macro.2. Import or clean data.3. Insert QUARTILE.INC or QUARTILE.EXC formulas, format output, and create a chart.4. Stop recording.5. Next time, run the macro on a new dataset with one click.**Google Sheets + Apps Script:**1. Open Extensions → Apps Script.2. Write a small script to read a column, compute Q1 with the QUARTILE function, and write results to a summary cell.3. Attach the script to a custom menu item or time-based trigger.**Pros:** Reusable and faster; hides complexity from non-technical teammates.**Cons:** Requires someone to maintain scripts; still bounded to the spreadsheet.---## 3. Scaling Q1 calculation with AI agents (Simular)Manual and no-code options are fine until you are juggling 50 files, 10 clients, and constant data refresh. This is where an AI computer use agent like Simular Pro becomes your operations specialist.Simular Pro can operate across your desktop, browser, and cloud tools the way a human assistant would: opening files, typing formulas, reading results, and pasting them into other systems, but with production-grade reliability.### 3.1 Agent to standardize Q1 across many Excel and Sheets files**Workflow idea:**1. You drop raw exports (CSV, XLSX) from your CRM or ad platforms into a folder.2. Simular Pro watches that folder.3. When a new file appears, the agent: - Opens it in Excel or Google Sheets. - Locates the metric column you care about (e.g., Revenue or CPC). - Inserts the correct Q1 formula (QUARTILE.INC or QUARTILE.EXC in Excel, QUARTILE in Sheets). - Stores the Q1 value in a dedicated cell or summary sheet. - Copies all Q1 values into a master reporting file or Google Sheet.**Pros:**- Handles dozens of files in one run.- Transparent execution: every click and keystroke is inspectable in Simular.- No custom code; you describe the workflow once.**Cons:**- Requires initial setup of a robust “golden path” workflow.- Best suited for teams with recurring, structured reporting.### 3.2 Agent-driven reporting pipeline for sales and marketingImagine a weekly pipeline review across markets:1. Simular Pro logs into your ad platforms and CRM in a secure, repeatable way.2. It exports performance data, saves it, and loads each file into Excel or Google Sheets.3. The agent runs Q1 calculations per channel, country, or segment using QUARTILE.INC.4. It pastes the quartiles into a clean dashboard file, updates charts, and even publishes a PDF or sends it via email or Slack.**Pros:**- End-to-end, human-like automation across browser, desktop, and cloud.- Q1 is always calculated the same way, reducing analytic drift.- You and your team stay focused on decisions instead of assembling numbers.**Cons:**- More complex flows benefit from a bit of upfront design and testing.### 3.3 Agents as QA and governance for analyticsSimular’s neuro-symbolic approach gives you transparent, deterministic steps. You can:- Ask the agent to recompute Q1 in multiple ways (QUARTILE vs QUARTILE.INC) and flag discrepancies.- Have it validate that all client reports actually contain a first quartile metric before sending.- Use webhooks from your existing pipelines to trigger the agent only when new data is ready.**Pros:**- Automated QA on top of your spreadsheets.- Fits neatly into existing pipelines via webhooks.**Cons:**- Requires you to think about governance rules (which is a good problem to have).By moving from manual clicks to no-code automation and finally to AI agents that behave like tireless spreadsheet specialists, you turn the humble first quartile into a living signal that updates itself across Google Sheets and Excel, at the scale your business actually operates.
In Excel, the classic way to return the first quartile (Q1) is the QUARTILE function. You pass it a range of numeric data and a quart argument of 1.1. Place your data in a column, for example A2:A101.2. Click an empty cell where you want Q1, such as B2.3. Type: =QUARTILE(A2:A101,1)4. Press Enter. Excel returns the value at the 25th percentile.Microsoft now recommends using QUARTILE.INC or QUARTILE.EXC for better statistical clarity. Their syntax is the same:- =QUARTILE.INC(A2:A101,1)- =QUARTILE.EXC(A2:A101,1)Use QUARTILE.INC to include the endpoints of your data range, and QUARTILE.EXC to exclude them. See Microsoft’s official docs for details and examples: https://support.microsoft.com/en-us/office/quartile-function-93cf8f62-60cd-4fdb-8a92-8451041e1a2a
Google Sheets uses the same QUARTILE syntax as Excel, making it easy to switch between tools.1. Paste or import your numeric data into a single column, for example A2:A101.2. Click the cell where you want the first quartile to appear, such as B2.3. Enter this formula: =QUARTILE(A2:A101,1)4. Press Enter. Sheets returns the first quartile (25th percentile) of that range.You can also use QUARTILE.INC and QUARTILE.EXC in newer versions of Sheets, mirroring Excel’s behavior:- =QUARTILE.INC(A2:A101,1)- =QUARTILE.EXC(A2:A101,1)To keep Q1 always up to date as you add new rows, use an open-ended range like A2:A instead of a fixed A2:A101. Google’s official reference for statistical functions, including QUARTILE, is here: https://support.google.com/docs/answer/3093991
QUARTILE, QUARTILE.INC, and QUARTILE.EXC are not identical; they use slightly different definitions of how to place quartile cutoffs.- QUARTILE and QUARTILE.INC include the endpoints of the data range when calculating quartiles. They treat the quartile as an inclusive percentile.- QUARTILE.EXC excludes the minimum and maximum data points from the calculation, using an exclusive percentile method.Because of this, the position of Q1 in the sorted list of values can differ by one or more index positions, especially for small datasets. That difference propagates into the numeric Q1 value you see.If you are doing business reporting and need consistency, pick one convention (usually QUARTILE.INC) and standardize it in your templates, documentation, and AI automations. Microsoft’s docs explain both methods in more detail: https://support.microsoft.com/en-us/office/quartile-inc-function-1bbacc80-5075-42f1-aed6-47d735c4819d
Start by turning your manual steps into a repeatable pattern, then add automation.1. Build a template: - In Excel, store data in a Table and reference it in a Q1 cell with QUARTILE.INC(TableName[Metric],1). - In Google Sheets, use a Raw tab and a Summary tab with formulas like =QUARTILE(Raw!B2:B,1).2. Use no-code tools: - Set up Zapier or Make to push new records from your CRM or ad platforms into your Raw tab. - Because your Q1 formulas reference the full column, they update automatically.3. Add notifications: - Create a scheduled automation that reads the Q1 cell and posts to Slack or email if it crosses a threshold.4. For true hands-off operation, use an AI computer agent such as Simular that can open files, refresh data, recompute Q1, and assemble reports across multiple workbooks and accounts.
AI agents like Simular Pro behave like tireless analysts who live inside your computer. Instead of you opening every Excel or Google Sheets file, pasting exports, and typing QUARTILE formulas, the agent does it for you.A typical workflow looks like this:1. You define a clear process: where data lives, which columns contain metrics, and where Q1 should be written.2. Simular Pro learns that workflow by literally performing clicks and keystrokes across desktop, browser, and cloud apps.3. On a schedule or webhook trigger, the agent: - Downloads fresh data from your CRM or ad platforms. - Opens Excel or Sheets and updates the raw data range. - Applies QUARTILE.INC or QUARTILE in the correct cells. - Copies Q1 values into your central dashboard or sends summaries to Slack and email.You get consistent, auditable Q1 calculations at scale, while your human team focuses on interpreting why the bottom 25 percent behaves the way it does and what to do about it.
