How to Hide Columns in Google Sheets: A Quick Guide

You can tell a lot about a business from its Google Sheets. Open one from a growing agency or sales team and you’ll often see a wall of columns: lead source, campaign, UTMs, commissions, internal notes, margins, and a few columns you’re slightly afraid to click.The trick isn’t to collect less data. It’s to control what’s visible, when, and to whom. Let’s walk through the best ways to hide columns in Google Sheets—starting manually, then scaling up with automation and an AI computer agent.## 1. Manual Hiding: Fast Fix For A Messy SheetUse this when you’re cleaning up your own view or preparing a one‑off report.**Steps to hide a single column**1. Open your spreadsheet in Google Sheets.2. Click the letter at the top of the column you want to hide.3. Right‑click the column header.4. Choose **“Hide column”**.You’ll see a small left/right arrow where the column used to be. That’s your reminder something is hidden.**Steps to hide multiple columns**1. Hold **Command (Mac)** or **Ctrl (Windows)**.2. Click each column letter you want to hide (they don’t have to be next to each other).3. Right‑click one of the selected headers.4. Click **“Hide columns …”**.**To show columns again**1. Find the small arrows between the remaining column letters.2. Click the arrows to unhide.**Pros**- Very fast for ad‑hoc cleanup.- No setup or scripting needed.**Cons**- Everyone with edit access can unhide.- Easy to forget which columns are hidden.- Painful to repeat every week or across dozens of sheets.## 2. Grouping Columns For Reusable ViewsIf you’re constantly expanding and collapsing the same sets of columns (for example, “finance-only” fields), grouping is more scalable than basic hiding.**Steps to group columns**1. Select all columns you want in the group.2. At the top, click **View → Group → Group columns**.3. A small bracket with a **+ / –** control appears above the group.4. Click **–** to collapse (effectively hiding), **+** to expand again.**Use cases**- Group sensitive cost columns you only open during monthly reviews.- Group heavy calculation columns that make views noisy for sales reps.**Pros**- One‑click expand/collapse of a logical column set.- Great for switching between “detail” and “summary” views.**Cons**- Still manual: you must click for each sheet and each session.- Not a real permission system—any editor can expand the group.## 3. Hiding Columns For Different Audiences With IMPORTRANGEWhen you truly don’t want certain people to ever see some columns, hiding isn’t enough; copy‑paste can reveal the data. A common workaround is to split data into multiple Sheets using `IMPORTRANGE`.**Pattern that works well**- **Master Sheet**: full data, including sensitive columns. Only trusted users can access.- **Proxy Sheet**: pulls a subset of columns from the Master using `IMPORTRANGE`. Only includes columns that are safe to share.- **Client or Team Sheet**: imports from the Proxy. This is what you actually share with customers or junior staff.Because the shared Sheet only ever sees the safe subset from the proxy, editors can’t tweak `IMPORTRANGE` to reveal hidden columns from the Master.**Pros**- Stronger separation between sensitive and shared data.- Works entirely inside Google’s ecosystem.**Cons**- More files to manage.- Formulas can be brittle if structure changes.- Still semi‑manual to maintain across dozens of clients.## 4. Automating Hiding Rules With Apps ScriptIf you find yourself repeating the same hiding pattern—“whenever column header contains ‘Cost’ or ‘Margin’, hide it”—you can encode the rule with Apps Script.**High‑level idea**- Open **Extensions → Apps Script** in your Sheet.- Write a script that: - Reads the header row. - Finds columns whose names match your conditions. - Calls `hideColumn()` on them.- Run the script or trigger it on open.This is great if you’re technical or have an operations person who can maintain scripts.**Pros**- Repeatable, rule‑based hiding.- Less manual clicking as your Sheet grows.**Cons**- Scripts can break when someone renames headers or moves columns.- Non‑technical teammates may hesitate to touch or debug scripts.## 5. Scaling All Of This With An AI Computer AgentAt some point, even Apps Script starts to feel like overkill to maintain—and underpowered for everything else you want to automate. That’s where an AI computer agent comes in.A Simular AI agent behaves like a power user sitting at your computer. It can:- Open Google Sheets in the browser.- Apply your exact business rules: “For client‑facing reports, hide internal margin, raw lead fields, and QA notes.”- Create or update Proxy Sheets using `IMPORTRANGE`.- Log every action so you can inspect and modify its behavior.Because Simular’s agents are designed for production‑grade reliability, they can run workflows with thousands of steps: preparing weekly client dashboards, refreshing sales reports, or generating sanitized copies of Sheets for external partners.**Example workflow**1. Every Monday, a webhook triggers your Simular Pro agent.2. The agent opens a master Google Sheet with all your campaign data.3. It creates or updates a proxy Sheet per client.4. For each proxy, it hides or omits internal‑only columns based on your rules.5. It posts links to a Slack channel or emails them to your account managers.**Pros**- No code required; you describe the task in natural language.- Works across desktop, browser, and cloud tools, not just Sheets.- Transparent execution: you can replay every step the agent took.**Cons**- Requires a bit of initial onboarding so the agent understands your patterns.- Best suited when you have recurring, multi‑step workflows—not just a one‑off hide.## Choosing The Right Level Of Automation- **One‑off cleanup?** Use manual hide.- **Regular personal views?** Use grouping.- **Need real separation of sensitive data?** Use Master + Proxy Sheets with `IMPORTRANGE`.- **Consistent rules across many Sheets?** Use Apps Script.- **Recurring, cross‑tool workflows?** Delegate to a Simular AI agent and let it run the playbook for you while you focus on strategy instead of column letters.
