Connect Google Sheets to your AI chat agent
Your team already tracks numbers in spreadsheets. Most of the time, reading them means opening a tab, and updating them means doing it by hand.
SourcetoMCP connects Sheets straight to Claude, ChatGPT, or any MCP-compatible agent, so it can read and write real spreadsheet data instead of guessing.

Why Sheets access matters for your agent
A spreadsheet your agent can only describe from memory isn’t much use. It needs live access to the actual cells, and the ability to write back to them, to be genuinely useful.
- Full read and write. Read any range, append or update rows, clear cells, find-and-replace, and manage tabs, all from the same connection.
- Structured output. Rows come back mapped to your header row’s column names by default.
- Built for templating. Duplicate a tab and fill in the copy, instead of recreating it by hand every time.
How it works
Connect Google Sheets. Authorise through Google's own sign-in, then pick the spreadsheet with Google's own file picker. SourcetoMCP never sees your password.
Your agent asks in plain language. It calls the right MCP operation behind the scenes, reading a range, appending rows, or editing a tab, and gets real spreadsheet data back.
Every write shows exactly what changed. The range, and how many rows and cells were affected, come back with every write, so you can verify the result rather than take it on faith.

Built to read and edit your spreadsheets
Read any range
Pull values from any tab and range, with the first row mapped to column names automatically, so your agent gets structured rows it can work with.
Log new data
Append rows to the end of a tracker without knowing which row is next, or overwrite a specific range outright.
Clean up and correct
Clear a range, or find-and-replace text across one tab or the whole spreadsheet in one call.
Build from a template
Duplicate a tab and fill in the copy, instead of copy-pasting a template by hand every time.
Manage the whole file
Add, delete, or reorder tabs, place an image in a cell, or pull a preview thumbnail, alongside the cells inside each sheet.
Full read and write access
Your agent can act on your spreadsheet when you ask it to, then read back exactly what changed.
Format cells as well as fill them
Bold headers, switch fonts, colour-code flagged values, add borders, and apply currency or percent formats, so content and appearance come from one connection.
Restructure data in place
Insert, delete or group a row or column, sort a range, merge cells, copy-paste a range with its real formatting, or split one column's text into several, without rebuilding the sheet around them.
Build a chart from real data
Line, bar, column, area, or scatter, anchored where you want it, and referenceable straight into a connected Google Slides deck.
Keep a tracker consistent
A dropdown that restricts entries, a standing rule that keeps flagged values highlighted, and warning-only protection on a header row.
Audit charts and format rules
List every chart and conditional formatting rule in a spreadsheet, update a chart's data range, or remove the ones that no longer earn their place.
Tidy up before you share
Check what's already protected, add a filter so viewers can sort without touching the structure, freeze a header row, and resize a column or row so nothing reads as cut off.
Comment and collaborate
Read, add, reply to, resolve and delete comments, and leave a plain note on a specific cell, all from the same connection.
Share it, or export it
Grant someone access, make it link-shareable, check who already has access, or export the whole spreadsheet as a PDF or Excel file.
Start from a blank sheet
Ask for a brand-new spreadsheet, filed under the same account and brand as one you've already connected, ready to work with immediately.

No. Connecting uses Google's own OAuth sign-in, and picking which spreadsheet to connect uses Google's own file picker. SourcetoMCP never sees your password.
No. It only acts when you prompt it to, and every write returns exactly what changed, so you can check the result yourself. Writes that set cell values report the range and how many rows and cells were affected; structural ones report what they touched, like the new tab, chart or rule.
Just don't ask it to. Your agent only calls a write operation when your prompt asks for one. Reading a range or listing tabs never changes anything.
Google Sheets is available on every paid plan. See Pricing for how many connections each plan includes.
