lark-sheets makes Claude work with Lark (Feishu) spreadsheets. It reads and writes cells, builds formulas, adds and restructures sheets and rows, and creates charts, pivot tables, filters, conditional formats, dropdowns, sparklines and floating images. It can also search and replace, roll back to earlier versions, and import or export Excel and CSV files.

It starts when you want to create or edit a sheet, summarize or chart data, or fix formulas. Its text is mostly Chinese. Before each action Claude must read the matching reference note, and it must read lark-shared first.

Good for

Analysts who want charts and pivot tables built from Lark sheet data
Finance and ops teams that live in spreadsheets
Anyone converting Excel or CSV into Lark sheets and back

Install lark-sheets

Claude Code

Copy this prompt.

Install the lark-sheets skill in Claude Code. Run this command:

npx @larksuite/cli@latest install
npx skills add larksuite/cli -y -g

Then check that it loaded and tell me how to use it.

2
Paste it into Claude Code. It shows the change and asks before running it.

Requires Node.js.

The README gives two routes. Option 1 (recommended) is npx @larksuite/cli@latest install. Option 2 builds from source and then runs npx skills add larksuite/cli -y -g, which the README marks as required. It does not say whether Option 1 also installs the skills, so this box runs both. Every lark-* skill needs the lark-cli program and sends Claude to lark-shared for sign-in. auth login --recommend picks commonly used scopes; use --domain to limit them.

Permissions

Medium risk

It can overwrite cells, delete rows and columns and revert history in sheets you can reach in Lark. Work on a copy and review changes before relying on them.

What it can do

Read your data
Create and change things
Delete things
Read-only mode

Watch out for

It can overwrite cells and remove rows
Writes, replaces, clears, deletes and history reverts change shared sheets. Work on a copy first.
It bundles Python scripts
The package ships 9 Python scripts. SKILL.md says Python is used to derive and check values, but does not list when each script runs. Read them before you let Claude run them.
It acts with your Lark permissions
README security note: after you authorize, the agent acts under your identity within the granted scope, and the README warns of prompt injection and data leaks.
