Data Conversion Tools
Data conversion tools translate structured records from one interchange format to another without a spreadsheet or a script. Convert CSV exports into JSON for an API, flatten nested JSON into a spreadsheet-ready table, or move between XML, YAML and TSV. Conversions run in your browser, which means confidential exports never leave your machine.

Data Conversion Tools: frequently asked questions
Are my data files uploaded to a server?
No. All converters in this category parse and rewrite the data inside your browser using JavaScript. Nothing is transmitted, logged or stored, which makes them safe for internal exports.
How large a file can I convert?
Files up to roughly 10 MB convert smoothly on a modern laptop. Larger files still work but the browser tab may pause for a few seconds while parsing.
What happens to nested objects when I convert to CSV?
Nested objects are flattened into dot-separated column names such as address.city, so no information is silently dropped. Arrays can be flattened or written as inline JSON depending on the option you pick.
