=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)
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.
