READ, EDIT AND REPAIR
Open a UTF-8 file or paste JSON. Read syntax colors, format compact text, or minify it for export. Validation explains syntax problems with a line and column; jump to the error to make your correction.

01 / JSON WORKSHOP
One workspace, from raw JSON to a useful result.
EXPLORE THE STRUCTURE
Browse objects and arrays with type labels and breadcrumbs. Search keys and values across the document. Add, duplicate or remove values, sort object keys, and copy a value or its JSON Pointer.
SEE WHAT CHANGED
Compare two documents for added, removed and changed values. Formatting and object-key order are ignored. Export a CSV difference report for further review.
KEEP WORK MOVING
Continue from a locally saved draft. Undo and redo recent changes, including incomplete text. Save JSON or an unfinished draft through Android’s file picker, or share valid JSON with another app.
