The delimiter is auto-detected from your first row - a tab, a pipe, or a comma. Literal pipe characters inside a cell are escaped so they do not break the table. Everything runs in your browser; nothing is uploaded.
Markdown Table Generator
Paste rows of data and get a clean GitHub-Flavored-Markdown table you can drop straight into a README, a wiki page, a pull-request comment, or any Markdown field. The whole conversion runs in your browser - your data is never uploaded, and nothing leaves the page.
How it works
The tool auto-detects the delimiter from your first row, so a comma-separated export, a tab-separated paste out of a spreadsheet, or an existing pipe-delimited table all work without any setting to change.
Formatting options
You control how the table is built before you copy it out:
- Header toggle - treat the first row as the header, or auto-name the columns Column 1 to N when it is off.
- Column alignment - left, center, or right, written into the alignment separator row with the correct colon markers.
- Literal pipe characters inside a cell are escaped as
\|so they do not break the table. - Columns are padded with spaces so the raw Markdown stays readable in a plain text editor.
- Copy the result with one click, or download it as a
.mdfile.
Privacy
Because everything is client-side JavaScript, you can use it offline once the page has loaded, and paste sensitive internal data without it touching a server.
Frequently Asked Questions
What input formats does it accept?
Paste comma-separated (CSV), tab-separated (TSV), or pipe-delimited rows. The delimiter is auto-detected from your first row, so you do not have to pick one. A tab is preferred, then a pipe, then a comma.
Is my data uploaded anywhere?
No. The table is built entirely in your browser with JavaScript. Your rows are never sent to a server, so you can paste internal or sensitive data safely.
What happens to pipe characters inside a cell?
A literal pipe in a cell is escaped as backslash-pipe so it does not split the column. The output is valid GitHub-Flavored Markdown that renders correctly on GitHub, GitLab, and most Markdown editors.
Can I control the column alignment?
Yes. Pick left, center, or right and the tool writes the matching alignment row - for example a center column uses a colon on both sides of the dashes. You can also toggle whether the first row is treated as the header.
How do I reuse the result?
Click Copy Markdown to put the table on your clipboard, or Download .md to save it as a Markdown file. Paste it into a README, a wiki, or a pull-request comment.
