About Markdown Table Generator

Create beautiful Markdown tables for your README files, documentation, wikis, and GitHub projects. The visual table editor lets you add and remove rows and columns, edit cell content inline, and set per-column alignment. Paste an existing Markdown table to modify it further.

Visual Editing

Click any cell to edit its content directly in the table. Changes are reflected in the Markdown output in real time. No more hand-editing pipe characters.

Column Alignment

Set left, center, or right alignment for each column independently. The alignment controls update the separator row automatically.

Import Existing Tables

Paste an existing Markdown table to visualize and edit it. The tool parses the markdown and populates the visual editor — great for tweaking tables from other sources.

One-Click Copy

Copy the generated Markdown to your clipboard instantly. Paste into GitHub, GitLab, Notion, or any Markdown-supported platform.

Frequently Asked Questions

Are these dev tools free?▼
Yes. All dev tools are completely free. No signup, no account.
Is my data sent to a server?▼
No. Base64 encoding, URL encoding, JWT decoding, hash generation, and regex testing all happen in your browser. Your tokens and secrets stay on your device.
Can I decode JWTs safely?▼
Yes. JWT decoding happens entirely in your browser. The token never leaves your device. Only the header and payload are decoded — signatures are not verified server-side.
