MCP Tools Reference: sheetsmcp.googleapis.com

Tool: update_formulas

Sets formulas in a range of a spreadsheet. Corresponds to spreadsheets.values.update in the REST API: https://developers.google.com/workspace/sheets/api/reference/rest/v4/spreadsheets.values/update

The following sample demonstrate how to use curl to invoke the update_formulas MCP tool.

Curl Request 
curl --location 'https://sheetsmcp.googleapis.com/mcp' \
--header 'content-type: application/json' \
--header 'accept: application/json, text/event-stream' \
--data '{
  "method": "tools/call",
  "params": {
    "name": "update_formulas",
    "arguments": {
      // provide these details according to the tool MCP specification
    }
  },
  "jsonrpc": "2.0",
  "id": 1
}'

Input Schema

UpdateFormulasRequest

JSON representation 
{
  "spreadsheetId": string,
  "range": string,
  "formulas": [
    array
  ]
}
Fields
spreadsheetId

string

Required. The ID of the spreadsheet to update.
range

string

Required. The A1 notation of the values to update.
formulas[]

array (ListValue format)

Required. The data that was read or to be written. This is an array of arrays, the outer array representing all the data and each inner array representing a row. Each item in the inner array corresponds with one cell. Supported value types are: bool, string, and double. Null values will be skipped. To set a cell to an empty value, set the string value to an empty string.

ListValue

JSON representation 
{
  "values": [
    value
  ]
}
Fields
values[]

value (Value format)

Repeated field of dynamically typed values.

Value

JSON representation 
{

  "nullValue": null,
  "numberValue": number,
  "stringValue": string,
  "boolValue": boolean,
  "structValue": {
    object
  },
  "listValue": array
}
Fields
Union field kind. The kind of value. kind can be only one of the following:
nullValue

null

Represents a JSON null.
numberValue

number

Represents a JSON number. Must not be NaN, Infinity or -Infinity, since those are not supported in JSON. This also cannot represent large Int64 values, since JSON format generally does not support them in its number type.
stringValue

string

Represents a JSON string.
boolValue

boolean

Represents a JSON boolean (true or false literal in JSON).
structValue

object (Struct format)

Represents a JSON object.
listValue

array (ListValue format)

Represents a JSON array.

Struct

JSON representation 
{
  "fields": {
    string: value,
    ...
  }
}
Fields
fields

map (key: string, value: value (Value format))

Unordered map of dynamically typed values.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

FieldsEntry

JSON representation 
{
  "key": string,
  "value": value
}
Fields
key

string
value

value (Value format)

NullValue

Represents a JSON null.

NullValue is a sentinel, using an enum with only one value to represent the null value for the Value type union.

A field of type NullValue with any value other than 0 is considered invalid. Most ProtoJSON serializers will emit a Value with a null_value set as a JSON null regardless of the integer value, and so will round trip to a 0 value.

Enums
NULL_VALUE Null value.

Output Schema

Represents a JSON object.

An unordered key-value map, intending to perfectly capture the semantics of a JSON object. This enables parsing any arbitrary JSON payload as a message field in ProtoJSON format.

This follows RFC 8259 guidelines for interoperable JSON: notably this type cannot represent large Int64 values or NaN/Infinity numbers, since the JSON format generally does not support those values in its number type.

If you do not intend to parse arbitrary JSON into your message, a custom typed message should be preferred instead of using this type.
