Written and maintained by the BitConvert team · Feb 27, 2026
The JSON Converter is a workspace for reshaping and cleaning up JSON data. Paste a payload and it will pretty-print it with consistent indentation, collapse it into a single minified line, or flag the exact spot where a syntax error breaks parsing. Beyond formatting, it transforms structured JSON into other common data formats so you can move information between systems that expect different inputs.
It converts JSON to CSV for spreadsheets, to YAML for configuration files, and to XML for legacy or enterprise integrations. It can also generate strongly typed model code from a sample object, producing interfaces and data classes for TypeScript, Go, Python, Rust, Swift, Java, Kotlin, C#, C++, PHP, and Ruby. Everything is processed locally in the page, which keeps sensitive API responses and internal data off external servers.
Key Features
Format or Minify
Beautify JSON with clean indentation for reading, or strip all whitespace to shrink payload size for production.
Syntax Validation
Instantly catches malformed JSON, such as trailing commas or unquoted keys, so you can fix errors before shipping.
Cross-Format Export
Convert a JSON document to CSV, YAML, or XML in one click for spreadsheets, config files, or legacy systems.
Type Code Generation
Produce ready-to-use type definitions and data classes for 11 languages including TypeScript, Go, Python, and Rust.
Common Use Cases
Format a compressed API response so you can trace a bug through deeply nested objects. Export a JSON data dump to CSV and open it in Excel or Google Sheets for reporting. Turn a sample response into a TypeScript interface or Python dataclass so front-end and back-end models stay in sync. Convert a JSON config into YAML for a Kubernetes manifest, or into XML for a system that only accepts XML input.
