About the JSON Converter

The JSON Converter transforms data between JSON, CSV, TSV, XML, and YAML formats in both directions. Different tools speak different formats — spreadsheets want CSV, configuration files use YAML, legacy systems produce XML — and this converter bridges them without manual reformatting.

Conversion runs entirely in your browser, so proprietary or sensitive datasets can be converted safely: nothing is uploaded to any server.

How to use it

  1. Paste your source data into the input panel.
  2. Choose the source and target formats (for example, JSON to CSV).
  3. Review the converted output in the result panel.
  4. Copy or download the result.

Frequently asked questions

How are nested JSON objects converted to CSV?
Nested structures are flattened using path-style column names (like address.city), since CSV is a flat, tabular format.
Does converting lose data?
JSON to YAML/XML round-trips preserve structure. JSON to CSV can lose nesting depth because CSV is tabular — check the output when converting deeply nested data.
Can I convert large files?
Yes, within your browser’s memory limits. Files of several megabytes convert in seconds since everything runs locally.
Is my data private?
Yes. The conversion happens on your device; your data is never transmitted.
