=CLAUDE() — use Anthropic Claude in Google Sheets

=CLAUDE() sends a prompt to Anthropic’s Claude models and returns the answer in the cell. No Anthropic API key is required — the model is built into GPT for Sheets.

Syntax

=CLAUDE(prompt, [value])

Parameter	Required	Description
`prompt`	yes	The instruction for Claude. A string or a cell reference.
`value`	no	Extra input appended to the prompt — usually a cell with your data.

Examples

Summarize customer feedback in A2:

=CLAUDE("Summarize this feedback in one sentence and name the main complaint", A2)

Rewrite marketing copy in a specific tone:

=CLAUDE("Rewrite in a friendly, non-salesy tone, keep under 30 words", A2)

Digest long call transcripts pasted in A2 (Claude handles long inputs well):

=CLAUDE("List the action items from this transcript as short bullet points", A2)

Localize marketing copy with tone preserved:

=CLAUDE("Translate to German, keep the playful tone and brand names in English", A2)

When to pick Claude

Long inputs: Claude handles large text fragments (reports, transcripts) well.
Careful rewriting and summarization where tone and nuance matter.
Cross-checking: run =GPT() and =CLAUDE() on the same rows and compare answers side by side — switching models is just a different formula name.
Drag the formula down for bulk runs, then use Replace all GPT formulas with results in the sidebar to freeze the answers.

=GPT() — the default model function, same arguments
=GEMINI() — Google’s Gemini models
=MISTRAL() — fast, low-cost bulk tasks
