Google Sheets

When to Use

• Find spreadsheets → list_spreadsheets
• Create new → create_spreadsheet (with optional sheet_names and initial_data)
• Read data → read_sheet (A1 notation range)
• Overwrite range → write_sheet
• Add rows → append_to_sheet

Important

• After creating, use the returned tab names (not "Sheet1") for read/write
• Range uses A1 notation: "Sheet1!A1:D10", "Income!A:D"
• values parameter is a 2D array: [["Name","Amount"],["Rent","1200"]]
