How to Use Claude in Google Sheets for Smarter Workflows

var url = 'https://api.anthropic.com/v1/complete'; var payload = { model:
"claude-2", prompt: prompt, max_tokens_to_sample: 300, temperature: 0.7 }; var
options = { method: "post", contentType: "application/json", headers: {
"x-api-key": apiKey }, payload: JSON.stringify(payload) }; var response =
UrlFetchApp.fetch(url, options); var json =
JSON.parse(response.getContentText()); return json.completion || "No
response"; } ```

  * Replace 'YOUR_API_KEY_HERE' with the actual key you copied earlier.
  * Click the **Save** icon (top left), and name the project if prompted.
  * Then click the **Run** button once to permit it to run.

You’ll need to approve some permissions—just follow the prompts. Once it's
authorized, you’re ready to go.

### Use Claude Like a Formula

Now comes the fun part. You can use Claude directly in your cells, just like
you use =SUM() or =VLOOKUP().

Here’s how it works:

  * In a cell, type something like this:
  * =callClaude("Summarize the following: " & A1)

Assuming A1 contains a paragraph of text, Claude will generate a summary right
there in the cell you entered in the formula. You can feed it anything—meeting
notes, product descriptions, long form content, customer feedback—and get a
cleaned-up version, ideas, headlines, or rewritten content.

You could also go the other way:

  * =callClaude("Generate three headlines for this content: " & B2)

Want ideas based on what’s in the sheet? Just write the prompt naturally,
reference the cell, and let Claude respond.

### Build Smarter Sheets with Claude

Once you have the Claude function running, you can start getting creative with
what it can help you do. Here are a few ideas:

#### a. Turn Data Into Insights

Say you’re collecting customer reviews in Column A. You can write:

  * =callClaude("What are the most common complaints in this list: " & JOIN(A1:A100, ", "))

It’ll scan all 100 entries and summarize the patterns for you. That’s hours of
manual reading done in seconds.

#### b. Help With Writing

Working on product descriptions? Marketing copy? Claude can generate drafts
based on the features listed in your sheet. Example:

  * =callClaude("Write a short product description for: " & C3)

Just list the product’s features or name in C3, and Claude will spin up
something you can tweak and use.

#### c. Brainstorming Directly in Sheets

If your spreadsheet includes ideas, topics, or goals, you can ask Claude to
expand on them.

  * =callClaude("Suggest three blog titles for the topic: " & D5)
  * =callClaude("List possible benefits for this idea: " & E2)

This works well for content calendars, strategy sheets, and project planning.

## A Few Things to Keep in Mind

Claude is text-based and relies on clean input. If your spreadsheet has
formulas mixed with raw text or incomplete entries, the responses might get
confusing. Keep your prompts simple and clear. If you find Claude’s answers
are too short or off-target, just edit your prompt a little. It learns nothing
about you, but it follows your instructions precisely. And don’t try to run
500 calls at once—Claude, like any API, works best when it’s not overwhelmed.
Stick to what’s needed, and avoid dragging whole spreadsheets into a single
cell.

## Done Right, It Feels Like Magic

When Claude is set up well in Google Sheets, it stops being a novelty and
starts feeling like something you actually use. The ideas come faster, your
sheets are cleaner, and the tasks that once took ten steps take two. And
because you don’t have to jump back and forth between apps, the workflow stays
tight. That’s really the goal—less busywork, more output. It doesn’t replace
thinking, and it’s not a substitute for writing from scratch when needed. But
for the repetitive, the rough drafts, or the "can you just help me with this
real quick?"—Claude fits in exactly where it should. Hope you find this
