Google Sheets Interaction Skill

Overview

This skill provides patterns and best practices for automating Google Sheets interactions through browser automation. Google Sheets is a canvas-based web app — standard DOM element references are often unreliable; prefer keyboard shortcuts and coordinate clicks.

Agent Workflow (Always Follow This Order)

1. Orient — Take a screenshot. Confirm you're on the right tab/sheet. Identify existing data range.
2. Plan — Decide what cells to read or write, in what order.
3. Execute in small steps — One logical action at a time (one row, one format operation, etc.).
4. Verify — Take a screenshot after each meaningful action to confirm the result before continuing.
5. Recover if needed — If something looks wrong,

   Cmd+Z

   immediately before doing anything else.

1. Session Setup / Opening a Sheet

Starting from scratch:

• Navigate to

  https://sheets.google.com

• Click "Blank spreadsheet" to create new, or click an existing file
• After clicking, wait for the new tab — Sheets often opens in a new tab. Switch to it before proceeding.

Opening an existing file:

• Navigate to

  https://drive.google.com

  , search for the file, and open it
• Or navigate directly via a known URL

Before acting on any sheet:

• Take a screenshot to confirm the sheet is loaded (look for the grid and toolbar)
• Confirm which sheet tab is active (bottom of screen)
• Use

  Cmd+Home

  to go to A1 and orient yourself

2. Reading / Understanding Existing Data

Before writing anything, read what's already there:

• Screenshot first — Get a visual overview of the data layout

• browser_get_text

  — Extracts cell text content; useful for reading values without clicking

• Cmd+End

  — Jumps to the last cell with data; tells you the extent of the dataset

• Cmd+Home

  — Returns to A1

To read a specific cell's value: Click the cell and read the formula bar (visible in screenshot), or use

browser_get_text

3. Navigation & Cell Selection

DO NOT type cell references into the Name Box — it often enters text into cells instead of navigating.

Preferred navigation methods:

Cmd+Home

Home

Cmd+End

Tab

Enter

Shift+click

Shift+click

Confirming current cell location:

• Take a screenshot and look at the Name Box (top-left, shows current cell address like "A1")
• Look at the formula bar (top center) which shows the selected cell's content
• The selected cell has a blue/green border — visible in screenshots

4. Data Entry

Basic pattern for tabular data:

1. Click on the starting cell (e.g., A1)
2. Type value → Tab (moves right)
3. Type value → Tab → Tab → ...
4. At end of row: press Enter (moves to next row, returns to column where you started)
5. Press Home to ensure you're at column A
6. Repeat

Entering a single value:

1. Click the target cell
2. Type the value
3. Press Enter or Tab to confirm (don't leave it unconfirmed)

Pasting multi-line data:

• Prepare data as tab-separated text (TSV)
• Click the target starting cell
• Paste with

  Cmd+V

• Verify result with a screenshot

Avoid:

• Typing tab characters inside a string to separate columns — they won't work as cell separators
• Leaving a cell in edit mode (blinking cursor) before navigating away — always confirm with Enter or Tab

5. Formulas

Entering a formula:

1. Click target cell
2. Type = followed by the formula (e.g., =SUM(A1:A10))
3. Press Enter to confirm

Common formulas:

=SUM(A1:A10)

=AVERAGE(B2:B20)

=COUNT(C2:C100)

=IF(A1>10,"Yes","No")

=VLOOKUP(key,range,col,0)

=A1&" "&B1

=TODAY()

Copying a formula down a column:

1. Click the cell with the formula
2. Press Cmd+C to copy
3. Select the range below (click first cell, Shift+click last)
4. Press Cmd+V to paste

Or: click the cell, then double-click the small blue square in the cell's bottom-right corner (auto-fill handle) — this fills down to match adjacent data.

6. Formatting

Bold / Italic / Underline:

1. Select cell(s) or row (click row number)
2. Cmd+B (bold), Cmd+I (italic), Cmd+U (underline)

Header row formatting (recommended pattern):

1. Click the row number to select the entire row
2. Cmd+B for bold
3. Click the Fill Color button (paint bucket in toolbar) → choose a color
4. View > Freeze > 1 row (so header stays visible when scrolling)

Number formatting:

Format > Number > choose format (Currency, Percent, Date, etc.)

Text wrapping:

Format > Wrapping > Wrap (or Overflow / Clip)

Column width auto-fit:

1. Click first column letter, Shift+click last column letter to select range
2. Right-click on any selected column header
3. "Resize columns A - X"
4. Choose "Fit to data" → OK

7. Sheet Tabs (Multiple Sheets)

Sheet tabs appear at the bottom of the screen.

Always confirm which sheet tab is active before reading or writing data.

8. Menus Reference

9. Common Keyboard Shortcuts

Cmd+B

Cmd+I

Cmd+Z

Cmd+Shift+Z

Cmd+A

Cmd+C

Cmd+V

Cmd+Home

Cmd+End

Home

Tab

Enter

Delete

Cmd+H

Cmd+Option+Shift+=

10. Error Recovery

Something went wrong — act immediately:

1. Cmd+Z

   — Undo the last action (do this before anything else)
2. Take a screenshot to assess current state
3. Re-orient:

   Cmd+Home

   to go to A1
4. Re-read the data before retrying

Common problems and fixes:

Cmd+Z

=

Escape

browser_tabs

Escape

Enter

11. Saving

Google Sheets auto-saves continuously. You do not need to manually save.

• Watch for "Saving..." → "All changes saved" in the top bar to confirm
• If you see a "Save" prompt, the file may be a non-Google format (e.g., .xlsx) — click Save to keep changes

12. Browser Automation Tips

• Google Sheets is a canvas app — DOM element references (

  ref_id

  ) often don't work for cells. Use coordinate clicks instead.
• Always screenshot before and after significant actions
• Use keyboard shortcuts over toolbar button clicks whenever possible — more reliable
• Toolbar buttons can be clicked by coordinate if needed; take a screenshot to locate them first
• Name Box (top-left showing cell address): Read it in screenshots to confirm position, but don't type into it for navigation
• After creating a new sheet, wait for the new browser tab to open, then switch to it before interacting
