Markdown Table Generator
Convert tab, comma, or pipe-separated data into GitHub-flavored Markdown tables with header and alignment options.
Paste data from a spreadsheet, a small CSV snippet, or pipe-separated text, then choose the delimiter, header behavior, and alignment marker. Generation stays in the browser and returns Markdown text only, without rendering a preview or uploading the input.
Browser-local generation
Markdown Table Generator
Paste non-sensitive table snippets only.
Spreadsheet copies usually use tabs.
Alignment markers are interpreted by the Markdown renderer.
How to use
Finish in three steps
- 01
Copy table data from a spreadsheet, CSV snippet, or delimited text list.
- 02
Choose tab, comma, or pipe separation and confirm whether the first row is the header.
- 03
Choose default, left, center, or right alignment when the target renderer supports it.
- 04
Copy the generated Markdown into GitHub, a README, an issue, or documentation and preview it there.
GitHub-flavored Markdown tables
The output uses the common GFM table shape: a header row, a separator row, and body rows wrapped with pipes. Short rows are padded so every generated line has the same number of columns.
Escaping and alignment boundaries
Pipe characters inside cells are escaped as \| so they stay inside the cell instead of creating extra columns. Alignment is written as Markdown syntax; the final display depends on the target renderer.
No rendered preview
This round generates Markdown text only and does not render HTML preview content. That keeps the browser-local surface narrow when working with untrusted pasted text.
FAQ
About this tool
Can I paste directly from Excel or Google Sheets?
Yes. Spreadsheet copies are usually tab-separated, so choose the tab delimiter for the cleanest conversion.
What happens when a cell contains |?
The tool escapes it as \| so it remains cell text instead of becoming a new column.
Does this parse complex CSV quoting?
No. It is for simple comma, tab, or pipe-separated text. Clean complex CSV with a dedicated CSV tool before generating Markdown.
Is my input uploaded?
No. Generation runs locally in the browser and does not call external APIs.
