Input and result notes

Flattening turns nested paths into keys. Existing separator characters in keys can be ambiguous; check arrays, empty objects and delimiter settings before relying on reconstruction.

Format and validation
  • JSON Unflattener

    Rebuild nested JSON objects from flat dot-path keys and their associated values.

  • JSON Key Sorter

    Sort object keys recursively throughout a JSON document while preserving the order of array elements.

  • JSON Object Merger

    Merge two JSON objects recursively and choose how arrays are combined in the resulting document.

  • JSON Diff

    Compare two JSON values and generate an RFC 6902 Patch.
