Convert between JSON, YAML, CSV and XML
Different systems speak different formats: APIs love JSON, config files prefer YAML, spreadsheets export CSV, and many enterprise services still use XML. This converter parses your input and re-serialises it into the format you need, preserving structure and types. It's ideal for wiring up integrations, migrating config, or inspecting an API payload as a spreadsheet.

Frequently asked questions
Does CSV support nested data?
CSV is flat by nature, so deeply nested structures are flattened or stringified. JSON, YAML and XML preserve full nesting.
Will it keep my data types?
Yes — numbers, booleans and strings are detected and preserved wherever the target format supports them.
Is my data uploaded?
Never. Parsing and conversion happen locally in your browser.
