CSV to Markdown Table Converter Online

What is CSV to Markdown conversion?

CSV to Markdown conversion turns comma-separated plain-text data into a formatted Markdown table. Each line becomes a table row, fields become cells, and a separator row of dashes defines the header — the GitHub Flavored Markdown (GFM) table format. Because CSV has no styling layer, a precise parser matters: quoted fields, embedded commas, and line breaks must be interpreted per RFC-4180 rather than split naively.

Delimiters and TSV support

The converter auto-detects the delimiter in your input, so one tool covers the common variants:

• Comma (,) — standard CSV exports.
• Tab (\t) — TSV, including direct pastes from Excel and Google Sheets.
• Semicolon (;) — common in European-locale exports.
• Pipe (|) — pipe-delimited logs and dumps.

No separate TSV page is needed: paste TSV here and it converts the same way.

Quoted values with commas and escaped quotes

Fields wrapped in double quotes are parsed strictly to RFC-4180: a value like "Product, Large" stays in a single table cell instead of splitting into two columns. Doubled quotes ("") inside quoted fields resolve to a literal quote character without breaking rows or columns.

Pipes, empty cells, multiline values and example

Edge cases are normalized so the output stays valid:

• Pipes (|) inside a cell are escaped as \| so GFM renderers do not create phantom columns.
• Empty fields are padded to keep every row the same width.
• Multiline quoted values are joined with <br> tags so each table row stays on one line.

Example input:

Name,Note
"Widget, Large","Ships
in 24h"

Example Markdown output:

| Name          | Note            |
|:--------------|:----------------|
| Widget, Large | Ships<br>in 24h |

Markdown output for GitHub and documentation

The generated output adheres to GitHub Flavored Markdown table syntax, ready to paste into README files, issues, PR discussions, wikis, and static-site docs. You can also copy the result back to Excel or TSV via the Copy to Excel action. Converting spreadsheet workbooks rather than plain-text files? Use the Excel to Markdown converter for pasted cells and .xlsx uploads.
