Private by design

This conversion runs entirely in your browser. Your text is not sent to a server.

Tip

YAML → JSON and XML → JSON keep nested structure. CSV expects a header row, or a JSON array of objects the other way.

How to convert with CSV ↔ JSON Converter

  1. Paste YAML, XML, or CSV (or JSON for the reverse direction).

  2. The converted result updates as you type — nothing is uploaded.

  3. Pick a direction, or Convert to to open YAML, XML, or CSV.

  4. Copy the result. Invalid input shows an error instead of output.

When should you use it?

  • YAML

    Turn config files into JSON, or JSON back into YAML.

  • XML

    Map elements to objects, or objects back to elements.

  • CSV

    Use the header row as keys, or emit a table from objects.

  • Stays here

    Spreadsheets and configs never leave this tab.

Your data stays private.

About converting YAML, XML, and CSV with JSON

YAML ↔ JSON, XML ↔ JSON, and CSV ↔ JSON share this family. YAML and XML keep nested structure. CSV expects a header row, or a JSON array of objects the other way. Invalid input shows an error instead of a guessed document. Convert to jumps between YAML, XML, and CSV.

Worked example: a YAML mapping with nested keys becomes a JSON object; a two-column CSV with a header becomes an array of objects. XML attributes and repeated tags follow the converter’s mapping — inspect the result before you ship it.

CSV ↔ JSON Converter FAQ

Paste CSV with a header row, choose CSV → JSON, and run the tool. Each data row becomes a JSON object.

Provide a JSON array of objects. Keys become CSV headers and values become cells.
