Open, inspect, edit and repair JSON files on your iPhone or iPad. JSON Viewer and Editor works offline, requires no account and keeps your documents on your device. VIEW JSON CLEARLY Browse objects and arrays in an expandable tree, search values and follow breadcrumb paths through deeply nested data. Switch to formatted code with syntax highlighting and line numbers whenever you need the raw document. EDIT AND REPAIR Edit JSON in the text editor or change values directly from the tree. Add, delete, duplicate and reorder nodes. JSON Fixer can repair common problems such as trailing commas, missing quotes and unquoted keys. COMPARE FILES Open two documents side by side and inspect additions, deletions and changed values. Import from Files, paste text or fetch JSON from a URL. VALIDATE AND QUERY Validate documents against JSON Schema Draft 7 and see useful error locations. Run JSONPath expressions and inspect matching values immediately. CONVERT AND EXPORT Convert JSON to YAML, CSV, XML or key-value text. Export results to PDF or Excel, save them to Files, print them or share them with another app. API AND HAR TOOLS Send GET, POST, PUT, PATCH and DELETE requests with custom headers and bodies. Inspect response status, timing and size, then open the response in the JSON viewer. HAR files open with a request summary for easier debugging.
