Setup & Installation
openclaw skills install @sorphwer/json-render-table
Or with the ClawHub CLI, for registry-managed skill folders outside a full OpenClaw workspace:
npx clawhub install json-render-table
What This Skill Does
Converts structured row/column data into PNG table images using json-render-cli. Accepts arbitrary datasets and renders them with configurable column widths, viewport sizing, and light/dark theme modes.
Generates table PNGs programmatically from JSON without needing a spreadsheet app, browser, or manual screenshot.
When to use it
- Exporting a JSON dataset as a table screenshot for a report
- Sharing a formatted data table as an image in a Slack message
- Rendering API response data as a PNG for documentation
- Generating a comparison table image for a release email
- Visualizing database query results as a clean table screenshot
