Structured Data
Format, validate, inspect, compare, query, flatten, sort, and convert JSON, XML, YAML, and CSV data without uploading a payload.
Formatters
Parse JSON and emit consistently indented, readable output while reporting the exact syntax error when the input is invalid.
Processing
Minify or key-sort JSON and move between nested documents and dot-path flat records while preserving JSON value types.
Validation
Check whether a JSON document parses successfully and locate malformed strings, delimiters, commas, or structural tokens.
Viewing
Explore nested JSON objects and arrays in a collapsible tree with clear value types and paths instead of scanning raw text.
Comparison
Compare two JSON documents by structure or raw text, review changed paths, and merge individual differences with undo.
Querying
Run JSONPath expressions against a local document and inspect the matched values and paths without executing remote requests.
Analysis
Extract unique keys and nested paths from JSON so schemas, mappings, and downstream transformations can be reviewed quickly.
Conversion
Convert JSON records into CSV, XML, or YAML while making array, nesting, scalar, and escaping behavior explicit.
Markup
Indent XML elements and attributes into readable markup while surfacing malformed tags and document structure.
Validators
Validate XML and YAML syntax locally, distinguishing well-formed source from parser errors before a configuration or data import.
Configuration
Format YAML configuration with stable indentation so mappings, sequences, multiline values, and nesting are easier to audit.
CSV
Parse CSV headers and quoted rows into JSON records, preserving repeated columns, embedded delimiters, and empty cells.
