What is a Markdown Table Generator?
A Markdown Table Generator is an online tool that lets you visually create and edit tables, then export them as properly formatted GFM (GitHub Flavored Markdown) syntax. Instead of manually typing pipes, dashes, and colons, you fill in cells in a spreadsheet-like grid and the tool produces clean, aligned Markdown table code automatically. The generated syntax works in GitHub READMEs, GitLab wikis, Notion, Obsidian, Jira, Confluence, and any platform that renders Markdown tables.

Frequently asked questions
What is GFM table syntax?
GFM (GitHub Flavored Markdown) tables use pipes (|) to separate columns and a header separator row with hyphens (---). Colons control alignment: :--- for left, :---: for center, and ---: for right alignment.
Can I set different alignment per column?
Yes. Click the alignment button above each column to cycle through left, center, and right alignment. The separator row will update automatically with the correct colon markers.
How many rows and columns can I add?
There is no hard limit. You can keep adding rows and columns as needed. The tool works best for tables up to around 20×20, which covers the vast majority of documentation use cases.
Does my data leave the browser?
No. All processing happens entirely in your browser using JavaScript. No data is sent to any server.
Where can I use the generated Markdown?
The output works on any platform that supports GFM tables: GitHub, GitLab, Bitbucket, Notion, Obsidian, Jira, Confluence, Hugo, Jekyll, Docusaurus, MkDocs, and more.
Can I paste an existing Markdown table to edit it?
This version focuses on generating new tables from scratch. For editing existing Markdown tables, you can manually update cell values in the grid after recreating your table structure.
