JSON Repairer

A JSON repair tool takes in a JSON string and repairs it, fixing any syntax errors and formatting it properly.

This tool is capable of resolving the following JSON issues:

• Quote Issues:

  • Add missing quotes around keys.
  • Replace single quotes with double quotes.
  • Replace special quote characters like “...” with regular double quotes.

• Escape Characters:

  • Add missing escape characters.
  • Strip escape characters from an escaped string like {"stringified": "content"}.

• Syntax & Structure:

  • Add missing commas and closing brackets.
  • Strip trailing commas.
  • Strip comments such as /* ... */ and // ....
  • Strip JSONP notation like callback({ ... }).

• Special Characters & Values:

  • Replace special white space characters with regular spaces.
  • Replace Python constants (None, True, and False) with their respective JSON values (null, true, and false).
  • Strip MongoDB data types like NumberLong(2) and ISODate("2012-12-19T06:01:17.171Z").

• String Concatenation:

  • Concatenate broken strings like"long text" + "more text on next line".

• Transformations:

  • Turn newline delimited JSON entries into a valid JSON array. For instance:

    { "id": 1, "name": "John" }
    { "id": 2, "name": "Sarah" }

    will be transformed to:

    [
      { "id": 1, "name": "John" },
      { "id": 2, "name": "Sarah" }
    ]
