CSV to Markdown (.md)

The fastest, 100% offline Chrome Extension to convert Excel cells & CSV data into GitHub-flavored Markdown tables.

🚀 Why CSV to Markdown?

When writing documentation in GitHub, GitLab, Obsidian, or Notion, formatting Markdown tables by hand is a pain.

While there are many online converters, pasting sensitive work data (like financial analytics or internal docs) into random websites violates NDA and privacy policies.

CSV to Markdown is a browser extension that runs 100% locally. Your data never leaves your device.

✨ Features

• ⚡ Instant Conversion: Paste your Excel cells or CSV data directly into the extension and get a clean Markdown table instantly.
• 🔒 100% Offline & NDA-Safe: No servers, no APIs, no tracking. Everything is processed client-side.
• 👁️ Live Preview: See exactly how your table will look before copying.
• 🗂️ Batch Conversion (PRO): Drag and drop multiple .csv files and download a single .zip archive of all your .md tables.
• 📐 Smart Alignment (PRO): Quickly set column text alignment (Left, Center, Right).
