CSV to Markdown Table Converter

What this tool does

This tool turns CSV data into a Markdown table you can paste straight into GitHub, project docs, or a README. Instead of hand typing pipes and dashes, you drop in your comma-separated rows and get a properly formatted table back. It helps developers documenting an API, writers building a comparison chart, and anyone who keeps notes in Markdown and wants tidy tables without the fiddly syntax.

The first line of your CSV is read as the header. Those values become the column titles, a separator row is inserted below them, and each remaining line becomes a row in the table.

How to use it

1. Paste or type your CSV into the input box. Put the column names on the first line, for example name,age.
2. Add your data rows below it, one record per line, such as Ada,36.
3. Watch the Markdown table appear as you type, or press Convert to refresh it.
4. Copy the output and paste it into your README, issue, doc, or comment.

A quick example

Given name,age on the first line and Ada,36 on the second, you get a piped table: a header row with name and age, a separator row of dashes, and a data row with Ada and 36. One common gotcha is a stray comma inside a value, since that splits the cell into two columns, so wrap such values carefully or clean them first.
