How to Rename Columns in Google Sheets: A Practical Guide

Why Column Names Matter More Than You Think

Open any export from your CRM, ad platform, or payment processor and you’ll see it instantly: cryptic labels like col_A, prop_17, or customField3. Before you can even read the data, you first have to translate the headers.

For a single Google Sheet, renaming columns is quick. But for agencies, operators, and sales teams juggling dozens of similar files, this “quick” fix becomes a quiet time sink.

Let’s walk through the best manual methods — and then how a Simular AI computer agent can handle the same work at scale.

Method 1: Directly Rename the Header Cell (Fastest For One-Offs)

1. Open your Google Sheet.
2. Click the header cell in the first row of the column you want to rename (for example, A1).
3. Type your new column name, such as Customer Name or Deal Value.
4. Press Enter to save.
5. Repeat for other header cells (B1, C1, etc.).

Pros

• Extremely simple and intuitive
• Perfect for small, one-time changes

Cons

• Tedious when you have many columns or many sheets
• Easy to introduce inconsistent naming across files

Method 2: Insert or Clean Up a Header Row

Sometimes your data starts in row 1 with no headers, or the headers are mixed into the data.

1. If you need a new header row, right-click on Row 1 and choose Insert 1 row above.
2. In the new Row 1, type the name for each column: Date, Campaign, Spend, Revenue, etc.
3. Select Row 1 and use the toolbar to bold the text or add a background color so headers stand out.
4. Go to View → Freeze → 1 row to keep your headers visible while scrolling.

Pros

• Makes a messy sheet immediately more readable
• Freezing the header row is great for long tables

Cons

• Still manual and repetitive
• Doesn’t solve bulk renaming across multiple sheets

Method 3: Named Ranges for More Structured Workflows

If you use a lot of formulas, dashboards, or Apps Script, Named Ranges can make your life easier.

1. Select the column (click the column letter, such as A).
2. Click Data → Named ranges.
3. In the sidebar, give it a meaningful name, like Leads_Email or Monthly_Revenue.
4. Click Done.
5. In formulas, you can now reference the range by name instead of A:A.

Pros

• Makes complex formulas self-documenting
• Reduces errors when ranges shift

Cons

• Still something you configure manually
• Named ranges live in one file; you must recreate them across others

Method 4: Right-Click and Context Options (When Available)

Depending on your setup, you may see options through the context menu or extensions.

1. Right-click on the column letter (for example, C).
2. Look for options like View more cell actions or add-on-driven commands.
3. Use these to define named ranges or trigger automations that rename columns.

Pros

• Can be faster than navigating menus
• Plays nicely with certain add-ons

Cons

• Still relies on you clicking through each column
• Limited when you need consistent naming across many files

Method 5: Automate Renaming With a Simular AI Computer Agent

Manual methods are fine when you touch a sheet once. But what if:

• Every Monday you download 10 new exports from your CRM?
• Each client has a slightly different naming convention?
• Your ops team keeps breaking dashboards because headers don’t match?

This is where Simular’s AI computer agents step in.

A Simular Pro agent behaves like a focused teammate at the keyboard.

1. Open Your Google Sheets

The agent launches your browser, signs into your workspace, and opens a target Sheet or a folder of Sheets.

2. Understand the Current Headers

It reads the first row of each sheet, detecting messy labels like prop_1, emailAddress, or cust_name.

3. Apply Your Naming Rules

You define a simple mapping once, for example:

• email, emailAddress → Email
• cust_name, customer → Customer Name
• amount, value → Deal Value

The agent rewrites the header row according to these rules across every relevant sheet.

4. Verify and Log Changes

Because Simular emphasizes transparent execution, every header change is logged: original name, new name, and which sheet or tab was edited.

Pros

• Handles dozens or hundreds of sheets without fatigue
• Consistent, repeatable rules across your entire workspace
• Transparent logs so every change is inspectable

Cons

• Requires a brief one-time setup of instructions and rules
• Best suited for ongoing, repeated renaming tasks

When To Switch From Manual to AI Automation

If you rename columns once a quarter, keep it manual.

If you:

• Work in an agency with recurring client reports
• Run sales ops with daily CRM exports into Google Sheets
• Maintain internal dashboards that break when headers change

Then delegating renames to a Simular AI computer agent pays for itself quickly. You standardize your schema once, let the agent enforce it everywhere, and free your own brain for strategy instead of cell editing.
