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. It uses a two-pane editor: you type or paste your comma-separated rows on the left, and a properly formatted table appears on the right the moment you type, with no Convert button to press. If a row does not line up with the header, an inline message points it out so you can fix it, and when the result looks right you can copy it or download it as a .md file. 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 left pane, or click Load example to drop in a sample. Put the column names on the first line, for example name,age, then your data rows below, one record per line, such as Ada,36.
2. The Markdown table appears in the right pane instantly as you type, so there is nothing to click to convert.
3. If an inline error appears, such as a row with the wrong number of columns, fix the flagged line and the table updates right away.
4. Use Copy to grab the Markdown, or Download to save it as a .md file, then paste it into your README, issue, doc, or comment. Clear empties both panes when you want to start over.

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.
