CSV → Markdown Table

About the CSV to Markdown Converter

This free online converter turns CSV, TSV, or semicolon-separated data into a GitHub-flavored Markdown table with aligned columns. Paste a spreadsheet export, click Convert, and get a table ready to drop into a README, pull request description, Confluence page, or static-site post. Everything runs in your browser — your data never leaves the page.

Why Markdown Tables?

Markdown tables are the lingua franca of developer documentation. GitHub, GitLab, Bitbucket, and most static-site generators render them to proper HTML tables. They are also diff-friendly in pull requests, unlike pasted images or HTML blobs.

Correctness Details

• Quoted fields handle commas, newlines, and embedded quotes ("")
• Pipes (|) inside cells are escaped as \| per GFM spec
• Newlines inside quoted cells collapse to spaces so the table stays single-row
• Column widths are padded so the raw Markdown source is also readable
• Alignment uses :--- / ---: / :---: markers

Common Use Cases

• Convert spreadsheet exports to README tables
• Document API parameter lists from a CSV source
• Turn test case matrices into pull-request descriptions
• Paste benchmark results into blog posts
• Export data from a database and drop it into docs

Frequently Asked Questions

What if my file uses semicolons instead of commas?

Pick semicolon from the Delimiter dropdown. European Excel exports typically use semicolons so that decimal commas don't collide with field separators.

Does it handle Excel-exported CSVs with BOMs?

Yes — a leading UTF-8 BOM is stripped automatically by the browser's text handling before parsing starts.

Is my data uploaded anywhere?

No. CSV parsing and Markdown emission happen locally — safe for internal data, employee lists, benchmark numbers, and confidential exports.
