JSONPath Tester

The JSONPath Tester evaluates JSONPath expressions against any JSON in real time. Supports dot notation, bracket notation, wildcards, array slices, recursive descent (..) and filter expressions like [?(@.price>40)]. Each match shows the value and its exact path in the JSON structure.

10 example expressions are included in the UI — click any to try it against the sample JSON immediately.

JSON Schema Generator

Paste a JSON example into the JSON Schema Generator and get a valid draft-07 schema. It auto-detects string, integer, number, boolean, null, array and object types. Special string formats are recognized: date-time, date, email and uri.

The generated schema includes $schema, $id, title, description, properties, required and additionalProperties: false.

IP Address Lookup

The IP Lookup shows geographic location, ISP, ASN, timezone, currency and calling code for any IPv4 or IPv6 address. Auto-detects your own IP on load. Results include an embedded OpenStreetMap showing the approximate location.

ASCII and Unicode Table

The ASCII Table is a complete reference for all 256 ASCII characters and extended blocks. Each row shows the character, decimal, hex, octal, binary and HTML entity. Search by character, code number or description. The Unicode tab covers arrows, math operators, box drawing, currency symbols and more.
