The Data Formatter & Converter tidies and checks JSON, YAML, and XML in a code editor with line numbers, folding, and search. Format type is detected automatically, and errors point to the exact line and column.
The Convert tab turns CSV into JSON, JSON into CSV, JSON into YAML, and YAML into JSON as you type. Paste text, open a file up to 5 MB, or drop it on the editor. Nothing is saved or uploaded.
Is my data sent to a server?
No. Formatting, validation, and conversion run in your browser, and nothing is saved.
Can it convert XML to JSON?
No. XML can be formatted and validated, but there is no single standard mapping from XML to other formats.
Will large numbers lose precision?
Formatting and minifying keep number literals exactly. Sorting keys and conversions warn you when a number would be rounded.
