Why @mdgate/csv

Runs where your JavaScript runs

No separate processing service. The converter is TypeScript you can call from Node.js, Cloudflare Workers, Edge runtimes, and browsers.

Local conversion

CSV files can stay inside your application or browser.

Content detection

csv has no strong file signature. Supply a path hint such as report.csv when composing converters.

Deterministic parsing

The same CSV file produces repeatable Markdown without model inference.

Small runtime surface

No Python. No native addons. No WASM. No third-party runtime dependencies.

CSV for AI agents

Turn CSV files into content your agent can actually work with.

FAQ

Yes. CSV files can be converted locally in the browser.

Does CSV to Markdown work in Cloudflare Workers?

Yes. @mdgate/csv runs directly in Cloudflare Workers.

Does it require Python?

No.

Does it require native addons or WASM?

No.

What does it output?

GitHub-Flavored Markdown.

Can I install only the CSV converter?

Yes. Install @mdgate/csv instead of the complete converter set.

Why pass a path?

Delimited text is signature-less. path is a sniff hint only. The converter never reads that path from disk.
