update_table_cells_by_notation_tool
Modify specific cells in Google Sheets tables using A1 notation to update values across multiple locations simultaneously.
Instructions
Update specific cells in a table.
This tool updates multiple cells in a table with new values using A1 notation.
Args:
spreadsheet_name: Name of the spreadsheet
sheet_name: Name of the sheet containing the table
table_name: Name of the table to update
cell_updates: List of cell updates with cell_notation and value
Returns:
JSON string with success status and update detailsInput Schema

| Name | Required | Description | Default |
|---|---|---|---|
| spreadsheet_name | Yes | The name of the Google Spreadsheet | |
| sheet_name | Yes | The name of the sheet containing the table | |
| table_name | Yes | Name of the table to update | |
| cell_updates | Yes | List of cell updates, each containing: - cell_notation: Cell reference in A1 notation (e.g., 'A1', 'B5') - value: New value for the cell (string, number, boolean, or None) EXAMPLE: [ {"cell_notation": "A1", "value": "New Value"}, {"cell_notation": "B5", "value": 50000}, {"cell_notation": "C10", "value": True} ] |

Implementation Reference
- Core handler function that implements the tool: validates cell notations, resolves spreadsheet/sheet/table IDs, parses cell references, and updates individual cells using Google Sheets API spreadsheets.values.update() for each cell update.
