When to use this tool
Fixing a table that came from somewhere else
You have a markdown table from another doc, an old README, or a Slack message, and the columns no longer line up, a row is missing, or the alignment markers got dropped somewhere along the way. Rebuild it cell by cell in the grid instead of hand-counting pipes and dashes, toggle the alignment per column, add the missing row, and copy out a table that's guaranteed to be correctly formatted.
Documentation tables
You are writing API documentation in a markdown file and need a parameter reference table with columns for name, type, required, and description. The visual grid keeps 20 rows organized without losing track of which column you are in.
Quick data formatting
You have a list of items with attributes from a spreadsheet or notes doc that needs to land in a GitHub issue, a Notion page, or a static site. Type the data into the grid and get properly formatted GFM markdown in seconds.
How it works
Edit in the grid
Click any cell to start typing. Use Tab to move to the next cell, or use the row and column controls to add or remove rows and columns. The first row is treated as the header row.
Set column alignment
Each column has an alignment toggle. Left alignment outputs :---, center outputs :---:, and right outputs ---: in the separator row. This is standard GitHub Flavored Markdown and renders correctly in GitHub, GitLab, Notion, and most markdown processors.
Copy the output
The markdown output updates live as you type. Copy it and paste it directly into any .md file, GitHub issue, pull request description, or any platform that supports GFM tables.
Frequently asked questions
Does the output work on GitHub?
Yes. The editor outputs GitHub Flavored Markdown (GFM) table syntax, which renders natively on GitHub in READMEs, issues, pull requests, and wikis. It also works on GitLab, Bitbucket, and any markdown renderer with GFM support.
Can I import an existing table?
If you have an existing markdown table and want to convert it from a different format, try the CSV to Markdown Table tool to bring in spreadsheet data, or the HTML Table to Markdown tool if you are starting from HTML.
How many rows and columns can I add?
There is no hard limit. The editor handles tables of any size. For very large datasets, pasting from a CSV file using the CSV to Markdown tool may be faster than entering data cell by cell.
Why does my table not render in my markdown editor?
Some markdown parsers do not support GFM tables by default. Standard CommonMark does not include table syntax. If your editor or static site generator is not rendering the table, check whether it has a GFM or table extension enabled. Most modern tools (GitHub, Notion, Obsidian, Hugo with goldmark) support it out of the box.
