Everything you need to edit, debug, graph, and parse JSON structures, packed into a single interface.
Paste structures directly. The browser immediately validates braces, checks scopes, parses JSON, and provides line index callouts on syntactical bugs.
Inspect objects in collateral collapsibles. Search keys or values to extract full dotted or bracket access coordinates (e.g. store.book[0].title) instantly.
Convert payloads to TypeScript type & interface, Java POJOs, Kotlin models, Go tag structs, Rust Serde deserializers, Python, C++, C#, Swift, YAML, and OpenAPI.
Filter and transform complex JSON structures inline. Supports jq pipe chains, conditional lookups with select(), and recursive key search.
Compare two JSON inputs side-by-side. Highlights structural additions and deletions in green/red to track API differences instantly.
Instantly convert JS Object literals, Python dictionaries, Java properties, or Java Map .toString() outputs into standard, valid JSON.
Automatically scans documents for lists. Select data coordinates to immediately draw line connections, area charts, or bar columns in high-fidelity SVG views.
Extract array metrics into a grid. Filter rows immediately using keyword matches and review formatted object columns inside an interactive grid interface.
Export grids to CSV or Excel instantly. We prepend a UTF-8 BOM to prevent character glitches, allowing spreadsheets to open seamlessly in Microsoft Excel.
Pasting credentials, API responses, or customer information? Json-a operates 100% locally. No files or text are transmitted to a server, keeping your data secure and private.
Format, analyze, plot, and compile code formats in one unified interface. Start optimizing your datasets instantly.
