How are quoted fields handled?

The parser follows RFC 4180, so quoted fields, commas inside quotes and doubled quotes are read correctly before being rendered as Markdown cells.

Will the table render in GitHub and other Markdown viewers?

Yes. It produces standard GitHub-Flavored Markdown table syntax — a header row, a separator row of dashes, then data rows — which renders in GitHub, GitLab, most wikis and Markdown editors.

Why is the output padded with spaces?

The columns are padded so each cell aligns in the raw text, making the Markdown source readable in a plain editor. The rendered table looks the same with or without padding.

Is my data uploaded anywhere?

No. Parsing and conversion happen entirely in your browser, so your spreadsheet data never leaves your device.

CSV to Markdown Table

Q: What happens to pipe characters in my data?

Pipes are escaped as backslash-pipe and any line breaks inside a cell are collapsed to spaces, because Markdown tables cannot contain raw pipes or newlines in a cell.

This tool converts CSV data into a Markdown table ready to paste into a README, wiki, GitHub issue or pull request. It produces aligned, padding-formatted GitHub-Flavored Markdown so the raw text is readable and the rendered table looks correct. You choose the delimiter and the first row becomes the table header.

How it works

The CSV is read by an RFC 4180-aware parser that handles quoted fields, commas inside quotes and doubled quotes. Each value is then made safe for Markdown tables: pipe characters are escaped as \| and any line breaks inside a cell are collapsed to spaces, because Markdown tables cannot contain raw pipes or newlines within a cell. The tool emits a header row, a separator row of dashes, then the data rows, padding each column so cells line up in the source. You can choose comma, semicolon, tab or pipe as the input delimiter.

Example

Given:

Name,Role,City
Ada,Engineer,London
Bo,Designer,Lagos

it produces:

| Name | Role     | City   |
| ---- | -------- | ------ |
| Ada  | Engineer | London |
| Bo   | Designer | Lagos  |

This renders as a proper table in any Markdown viewer. Everything runs locally in your browser — nothing is uploaded, which makes it safe for confidential exports and internal data.
