JSON Pointer Value Extractor User Guide

Query one JSON document with a JSON Pointer, retaining number spelling, string escapes and internal whitespace without reconstructing the source.

How to use

  1. Paste one JSON document and a plain-string Pointer; an empty path selects the root value.
  2. Run the query and check the type and complete original fragment.
  3. Copy the result; query again after changing either input.

Formats and limits

  • JSON is limited to 1 MiB and 50 levels; documents containing duplicate decoded object keys are rejected.
  • Only RFC 6901 plain strings are supported; no percent decoding, URI fragments, JSONPath or data modification.
  • Data is processed only in local memory, never uploaded, and cleared on leaving or reload.

Output

The type and copyable original fragment of one JSON value.

Frequently asked questions

How do an empty path and a slash differ?
