How to build tool inventory in Google Sheets & Excel

1. Manual methods: building a solid tool inventory foundation

Before you automate anything, you need a clean, usable spreadsheet. Let’s start with traditional, hands-on setups in both Google Sheets and Excel.

‍

A. Set up a basic tool inventory in Google Sheets

1. Create the sheet
   • Go to https://sheets.google.com and click Blank.
   • Rename the file to something clear like Tool Inventory – 2025.
2. Define your columns (each column = one field):
   • Tool ID (unique code)
   • Tool Name
   • Category (power tool, IT, camera, etc.)
   • Location (warehouse, van, site A)
   • Assigned To
   • Status (available, in use, under repair, lost)
   • Quantity
   • Purchase Date
   • Supplier
   • Next Maintenance Date
3. Use data validation for clean entries
   • Select the Status column.
   • Go to Data > Data validation (docs: https://support.google.com/docs/answer/186103).
   • Set Criteria to List of items and enter Available,In use,Under repair,Lost.
   • This prevents messy, inconsistent status labels.
4. Add filters for quick views
   • Select the header row.
   • Click Data > Create a filter (help: https://support.google.com/docs/answer/3540681).
   • Now you can filter tools by location, status, or assignee with one click.
5. Highlight issues with conditional formatting
   • Select the Next Maintenance Date column.
   • Go to Format > Conditional formatting.
   • Add a rule: Format cells if Date is before Today → choose a red fill.
   • Overdue maintenance pops visually on the sheet.

‍

B. Build an inventory table in Excel

1. Create and format a table
   • Open Excel and start a blank workbook.
   • Add similar columns as above.
   • Select your data range and press Ctrl+T or use Insert > Table (guide: https://support.microsoft.com/en-us/office/create-and-format-tables-0b8a6b65-3c9e-4f1f-bdfb-970b0c08fa8c).
2. Apply data validation to key columns
   • Select the Status column.
   • Go to Data > Data Validation (docs: https://support.microsoft.com/en-us/office/apply-data-validation-to-cells-29fecbcc-d1b9-42c1-9d76-eff3ce5f7249).
   • Choose List and type Available,In use,Under repair,Lost.
3. Use filters and sorting
   • Tables auto-add filter arrows. Use them to sort by Next Maintenance Date or Location (more: https://support.microsoft.com/en-us/office/filter-data-in-a-range-or-table-f2fbe53d-8d0b-4b3c-8d82-0bce1af72d5b).
4. Create basic alerts
   • Use conditional formatting on Quantity to highlight anything below a threshold (e.g., < 2) in orange or red.

‍

These manual methods give you full control and are ideal when you’re still defining what to track or have a small team.

‍

2. No-code methods: light automation without engineering

Once the basics work, you can cut down repetitive typing with no-code automations.

‍

A. Automate intake with forms

• In Google Sheets:
  • Use Google Forms linked to your sheet to log tool check‑outs.
  • Create a form with fields like Tool ID, User, Action (check-out/check-in), Location.
  • Connect responses to the inventory sheet and use formulas like =SUMIF or =COUNTIFS to update quantities.
• In Excel:
  • Use Forms for Excel (via Microsoft 365) to collect tool movements.
  • Responses flow into an Excel table, where structured formulas adjust inventory counts.

B. Use built-in automation features

• Google Sheets macros
  • Record recurring actions (like formatting a new month’s sheet) via Extensions > Macros > Record macro (help: https://support.google.com/docs/answer/9363248).
  • This is perfect for monthly inventory snapshots.
• Excel macros and Power Automate
  • Record macros to handle repetitive formatting or reporting.
  • Combine Excel Online with Power Automate to trigger flows when rows are added (e.g., send an email when a tool is marked “Lost”). See Power Automate docs at https://learn.microsoft.com/power-automate/.

C. Connect your tools with third‑party automation

• Use services like Zapier or Make to:
  • Create rows in Google Sheets or Excel when a ticket is opened in your helpdesk (new tool request or incident).
  • Post alerts in Slack/Teams when quantities fall below a minimum.
  • Log purchases from your accounting or procurement app into the sheet.

‍

Pros:

• No engineering team required.
• Great for connecting forms, chat, and inventory.

‍

Cons:

• Logic can become complex across many Zaps/flows.
• Still needs a human to design and maintain rules.

‍

3. At-scale automation with an AI agent (Simular)

Manual and no-code automation reduce clicks, but you’re still the orchestrator. An AI agent like Simular Pro acts more like a digital ops assistant that actually uses your computer.

‍

A. Let Simular maintain your spreadsheet

‍

Simular Pro can:

• Open Google Sheets in the browser or Excel on desktop.
• Read tool rows, interpret statuses, and apply your business rules.
• Cross-check tool IDs from emails, PDFs, or vendor portals.
• Update quantities, locations, and maintenance dates across multiple files.

‍

Example workflow:

• Every evening, the agent:
  1. Opens your Google Form responses.
  2. Aggregates check‑ins and check‑outs.
  3. Updates the master inventory in Sheets or Excel.
  4. Highlights discrepancies (negative stock, duplicates) in a separate “Exceptions” tab.

‍

Pros:

• Behaves like a reliable human assistant that never gets tired.
• Works across apps: browser, desktop Excel, email, shared drives.
• Transparent execution—every click and edit is inspectable, so you can audit its logic.

‍

Cons:

• Requires an initial onboarding period (like training a new hire).
• Best value when your inventory volume and change rate are high.

‍

B. Use Simular for multi-step, multi-app workflows

With Simular Pro, you can design long-running workflows (thousands of steps) such as:

• Procurement to inventory: When a purchase order is approved, Simular logs into the vendor portal, downloads invoices, extracts tool data, and updates Excel quantities plus next maintenance dates.
• Field check reconciliation: The agent compares on‑site counts (from CSV uploads or photos) with your Google Sheets inventory, flags mismatches, and generates a summary report.

These are the types of workflows where traditional no-code tools struggle, but a full computer-use AI agent excels.

By combining a well-structured spreadsheet with no-code automation and a Simular AI agent, you move from “we have a list of tools” to “our entire tool lifecycle, from purchase to retirement, runs itself with human review only where it really matters.”
