In short: A Markdown table generator converts rows and columns — typed into a grid or pasted from Excel, Google Sheets or CSV — into a GitHub-flavored Markdown table with aligned pipes.
About Markdown Table Generator
Markdown tables are tedious to type: every row needs pipes, the header needs a separator row and alignment colons, and keeping columns lined up by hand is fiddly. The quickest route is usually to start in a spreadsheet, copy the cells and paste them here.
Tab-separated data (what Excel, Numbers and Google Sheets put on the clipboard) and comma-separated CSV with quoted fields are both detected automatically. Pipe characters inside cells are escaped as \| so they do not break the table.
How to use Markdown Table Generator
- Paste cells copied from a spreadsheet, or CSV text. The first row becomes the header.
- Choose alignment and whether to pad columns to equal width.
- Copy the Markdown and check the preview below it.
Examples
Select a range, press Ctrl/⌘+C, paste here — the tab-separated cells turn straight into a table.
Choose Right to get a separator like | ---: |, which right-aligns columns on GitHub.
Frequently asked questions
Which Markdown flavors support tables?
GitHub-flavored Markdown (GitHub, GitLab, many static site generators, Obsidian, Notion import). Original Markdown has no tables.
Can I put line breaks inside a cell?
Not with standard syntax. Use <br> inside the cell if your renderer allows HTML.
Why pad columns?
Padding only makes the raw text easier to read; renderers ignore it.
Is my data uploaded?
No. Everything runs locally. You can check this yourself: open your browser’s developer tools, switch to the Network tab and use the tool — no request carries your input.
