Every time your team starts a "new" spreadsheet from scratch, they quietly pay a tax in time and inconsistency. Headers shift, formulas change, someone forgets the filter you swear was there last quarter. Templates in Google Sheets and Excel remove that chaos. You design the layout, logic, and formatting once—then everyone clicks File > New and gets the exact structure you trust. Sales forecasts, campaign calendars, client reports and P&Ls all start from the same source of truth, which means faster onboarding, cleaner data, and fewer "which version is right?" debates in Slack.
Now imagine you never touch the template setup again. An AI computer agent like Simular opens Sheets or Excel for you, builds the tabs, freezes headers, applies data validation, and saves the file to the right team folder in minutes, not hours. You say, "spin up a Q4 pipeline template for the new reps," and the agent does the clicking, typing, and saving while you stay focused on pricing, messaging, and closing the next deal.
Before you bring in automation or an AI agent, it helps to master the classic ways humans build templates.

On Windows, Excel will usually propose the Custom Office Templates path (for details, see Microsoft’s guide to saving templates: https://support.microsoft.com/en-us/office/save-a-workbook-as-a-template-58c6625a-2c0b-4446-9689-ad8baec39e1e).
To use it later:
If your team lives in templates, set a default folder so they’re easy to find:
Now every template in that folder appears under File > New > Personal, giving your whole team a curated template gallery.
Google Sheets doesn’t use a .xltx file, but the pattern is similar: design once, copy many times.

To reuse it, you have two simple options:
Google’s official docs on creating files from templates: https://support.google.com/docs/answer/6000292
For business owners and agencies, think in categories:
Manually, you create each once in Excel or Google Sheets, store them in predictable folders, and agree as a team: “Always start from a template, never from a blank file.”
Once the basics are in place, you can stop hunting for templates and let no-code tools do the filing and copying.
Use tools like Zapier or Make (Integromat) to trigger from your CRM:
{{Company}} – Onboarding Tracker.Result: every time sales closes a deal, the onboarding template appears automatically—no one touches Sheets.
If your team is on Microsoft 365:
.xltx templates in a shared SharePoint or OneDrive folder.This keeps Excel in your stack while removing the repetitive admin around file creation.
Don’t overlook the native galleries:
You can start from these, customize for your business, then treat your customized version as the "golden" template for future automations.
Manual and no‑code flows are powerful, but they still assume a human sets up the template logic. An AI agent like Simular can go further: it behaves like a power assistant at the keyboard.
Imagine you describe the template in plain language:
"Create a weekly sales dashboard in Excel with a raw data tab, a pivot summary, conditional formatting for deals over $50k, and save it as a template for the Enterprise team."
A Simular AI agent can:

Once your template exists, the agent can:
Compared with no‑code tools, the AI agent can also:
Templates age. New KPIs, pricing models, and channels appear.
You can:

By combining manual craftsmanship, no-code triggers, and an AI agent like Simular to operate Excel and Google Sheets directly, you turn templates into a living system—always current, always ready, and created without burning your team’s attention on admin.

Start with the best version of your existing spreadsheet, then freeze it in time as a reusable template. In Excel, open the workbook, remove one-off data and sensitive client details, and leave only sample rows if you need to explain usage. Double-check formulas, named ranges, and conditional formatting so they work even when new rows are added. Then go to "File > Save As", choose a location (ideally your Custom Office Templates folder), and in "Save as type" pick "Excel Template (*.xltx)". Give it a clear, structured name like "RPT_Sales_Pipeline_Monthly.xltx" so teammates can recognize it. Save. Next time, no one should copy the old live file; they simply open Excel, click "File > New > Personal" and select the template. This pattern keeps logic stable while every user starts from a clean, client-specific copy.
Think of your Google Sheets template as the training wheels for your process. Start with a blank Sheet and outline the workflow: tabs for raw data, summary, notes, maybe a dashboard. Add headers and immediately freeze the top row via "View > Freeze > 1 row". Add data validation for key fields (e.g., status dropdowns, owner, region) under "Data > Data validation" so people can’t improvise new labels. Build your core formulas and conditional formatting, aiming to keep inputs in one section and outputs in another. When it feels solid, rename it to include "Template" and move it into a shared drive or folder dedicated to templates. Your team should either use "File > Make a copy" to start from it, or, in Google Workspace domains with the feature enabled, submit it to the Template gallery so it appears in everyone’s "Template gallery" menu as an official starting point.
The secret is to separate input cells from logic, then lock the logic. In Excel, select the whole sheet, press Ctrl+1, go to the "Protection" tab, and uncheck "Locked" so everything starts unlocked. Then select only formula cells and important labels, open "Format Cells" again, and re-check "Locked". Next, go to "Review > Protect Sheet", set a password if appropriate, and choose what users are allowed to edit (typically inserting rows and selecting cells, but not formatting or changing objects). In Google Sheets, use "Data > Protect sheets and ranges" to restrict edit access to certain ranges or the entire sheet, leaving input cells open. Name protected ranges like "Formulas_do_not_edit" so intent is clear. Turn your protected file into a template (Save As in Excel, or make it your Sheets master). This way users can’t accidentally break the engine while still updating the inputs you expect.
Treat templates like product versions, not static files. First, copy your current Excel or Google Sheets template and label it as a working draft, e.g., "Template – Campaign Tracker v2 WIP". Apply your changes there: new KPIs, extra columns, or improved formatting. Test it with a few real use cases and, if possible, a small pilot group of users. Once you’re confident, archive the old template by moving it to an "archive" folder or renaming it with an "OLD" prefix so it’s clearly deprecated. Replace it in your official locations: for Excel, save the updated version as a .xltx file in your Custom Office Templates folder; for Sheets, replace the file that’s referenced in your Template gallery or no-code automations. Communicate the change: link to the new template, document what’s different, and set a sunset date for old versions so your ops, sales, and marketing teams don’t quietly keep using outdated structures.
You want templates that don’t just look standard but stay in sync with live data. For Google Sheets, start by using "Extensions > Add-ons" or connectors that pull in CRM or finance data, or connect via tools like Zapier and Make. For example, each time a new deal is created, an automation can copy your Sheets or Excel template, name it after the account, and write key fields (owner, ACV, close date) directly into the new file. On Microsoft 365, Power Automate can read data from Dynamics, Salesforce, or an Excel table, then create or populate Excel files based on your templates. If you use an AI agent like Simular, it can even open the template itself, refresh queries, run pivots, and save or distribute updated reports. The pattern is always the same: keep the template structure stable, then wire data sources and automations around it so your team never exports CSVs by hand again.
