CSV to Markdown Table Converter
This tool instantly converts CSV (Comma-Separated Values) data into a GitHub-Flavored Markdown (GFM) table. Simply paste your CSV — including the header row — choose your delimiter and column alignment, and get a properly formatted Markdown table ready to drop into any README, wiki, or documentation page.
GitHub-Flavored Markdown tables require a header row, a separator row with optional alignment markers (`:---`, `:---:`, `---:`), and one or more data rows. This converter handles quoted fields, multiple delimiter types (comma, tab, semicolon, pipe), and automatically pads columns for clean, readable output.
How it works
GFM table structure: row 1 = header cells separated by `|`; row 2 = separator cells using `-` with optional `:` for alignment (`:---` = left, `:---:` = center, `---:` = right); rows 3+ = data. All cells are padded to the widest value in their column for readability.
Use cases
- Formatting spreadsheet data for GitHub READMEs and wikis
- Converting database query results (exported as CSV) into documentation tables
- Preparing Markdown tables for technical blog posts and tutorials
- Embedding structured data in Markdown-based static site generators (Jekyll, Hugo, Astro)
- Quickly sharing tabular data in Slack, Notion, or other Markdown-compatible platforms
Frequently asked questions
How do I convert a CSV file to a Markdown table?
Paste your CSV data into the input, making sure the first row contains the column headers, then pick the delimiter and alignment you want. The tool instantly builds a GitHub-Flavored Markdown table with a header row, a separator row, and your data rows, ready to copy into any README or wiki.
What delimiters does the converter support besides commas?
In addition to commas, the converter handles tab, semicolon, and pipe delimiters, which are common in exports from Excel, European locales, and databases. It also correctly parses quoted fields, so values that contain the delimiter itself are kept intact.
How do I align columns in a Markdown table?
Alignment is controlled by colons in the separator row: `:---` aligns left, `:---:` centers, and `---:` aligns right. Choose the alignment in this tool and it writes the correct markers for you, so you do not have to edit the separator row by hand.
Is my CSV data uploaded anywhere when I use this tool?
No. The conversion runs entirely in your browser and nothing is sent to a server, so it is safe to paste internal or sensitive data. You can even use it offline once the page has loaded.
Will the generated table render on GitHub, Notion, and other platforms?
Yes. The output follows the GitHub-Flavored Markdown (GFM) table syntax, which is supported by GitHub READMEs and wikis, most static site generators like Jekyll, Hugo, and Astro, and many Markdown-compatible apps. Plain original Markdown does not define tables, so a few minimal renderers may not display them.
