[FEATURE] Google Sheets Edit

### Preflight Checklist

- [x] I have searched [existing requests](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20label%3Aenhancement) and this feature hasn't been requested yet
- [x] This is a single feature request (not multiple features)

### Problem Statement

Claude can't edit google sheets directly.
I often work with Claude on extracting info from big csv files and parsing them into smaller sheets. I encounter multiple instances where I'd like Claude to do a big edit across the entire spreadsheet and I want the edits to be incorporated. Right now, I need to manually upload the new csv's created by Claude into Google Sheets.

### Proposed Solution

I'd like Claude to be able to directly edit sheets in google so I can replace entire sheets, add new ones, edit content in sheets etc.

### Alternative Solutions

_No response_

### Priority

Medium - Would be very helpful

### Feature Category

API and model interactions

### Use Case Example

_No response_

### Additional Context

_No response_

No file, test, or entry point is identified. The request is for direct Google Sheets editing—replacing sheets, adding sheets, and editing sheet content—so first locate the API and model-interaction integration point and define how these operations would be supported and verified.
