JSON & Data
Structured data is the format developers read and debug most, and it is rarely delivered in a readable shape. These tools clean up JSON, explain exactly where a document is malformed, and convert between the interchange formats you actually encounter — CSV exports, YAML config, and legacy XML payloads. Every conversion runs in your browser, so API responses and config files never leave your machine.
JSON Formatter Pretty-print, validate and minify JSON with syntax highlighting and precise error locations. JSON Validator Check whether JSON is valid and get the exact line, column and cause of any syntax error. JSON Minifier Strip whitespace from JSON to shrink payloads, with a live byte-size saving comparison. JSON Viewer Explore large JSON as a collapsible tree, with search, type badges and copyable paths. JSON to CSV Convert a JSON array into CSV, flattening nested objects into dotted column headers. CSV to JSON Turn CSV or TSV into a JSON array, with header detection and automatic type inference. JSON to YAML Convert JSON into readable YAML for Kubernetes manifests, CI files and config. YAML to JSON Convert YAML into JSON and surface indentation or syntax errors with line numbers. XML Formatter Indent and validate XML, including SOAP envelopes, RSS feeds and SVG markup. XML to JSON Convert XML documents to JSON, with clear handling of attributes and text nodes.
