# batch_write_values

Overwrites several A1 ranges in ONE call — one write against the per-minute quota instead of one per range, so always prefer this over looping write_values. data is a list of {range, values} pairs; all are written with the same value_input_option (USER_ENTERED parses formulas/numbers/dates, RAW stores literally). Returns totalUpdatedCells and a per-range responses[] breakdown. Like write_values, null entries skip cells rather than clearing them.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `data` | array | yes | The ranges to write, each with its own 2-D values matrix. |
| `spreadsheet_id` | string | yes | The spreadsheet id — the long id from the URL (docs.google.com/spreadsheets/d/<spreadsheetId>/edit) or from create_spreadsheet / search_spreadsheets output. |
| `value_input_option` | string | no | USER_ENTERED (default) parses formulas/numbers/dates; RAW stores literal strings. |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "batch_write_values",
    "arguments": {
      "data": [],
      "spreadsheet_id": "<spreadsheet_id>"
    }
  }
}
```

## Why batch_write_values is rated Medium

Modifies spreadsheet data reversibly across multiple ranges with batch efficiency.

From the tool's own definition: "Overwrites several A1 ranges in ONE call, writes values"

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents use batch_write_values to create or update resources in Mcp Google Sheets, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Google Sheets environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp Google Sheets:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "batch_write_values": {
      "limits": [
        {
          "counter": "batch_write_values_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
