HJSON to JSON

Client

Import HJSON configs as strict JSON.

Learn more: HJSON to JSON

Convert relaxed HJSON configuration text—with comments, optional quotes, and fewer commas—into strict JSON that standard parsers and APIs can consume.

Required input

Paste the HJSON document as text, including comments or unquoted keys. Run the conversion, then copy the strict JSON result or format it for review.

What the result means

HJSON conveniences are removed in the output. Comments cannot be represented in standard JSON, so keep the original HJSON file when commentary matters.

Local processing

The page parses and transforms the pasted document in your browser. Use a smaller representative sample first when the source is large.

Input and workflow

Paste the HJSON document as text, including comments or unquoted keys. Run the conversion, then copy the strict JSON result or format it for review. Start with Load example or prefill the primary input with ?q= / ?qb=.

Scope and limits

HJSON conveniences are removed in the output. Comments cannot be represented in standard JSON, so keep the original HJSON file when commentary matters.

The operation runs in your browser. Large documents may slow the tab, so test a representative sample before processing more data.

Common use cases

  • Convert a human-edited HJSON config before passing it to a strict JSON-only service.
  • Remove comments and relaxed syntax from a sample used in tests or documentation.
  • Compare an HJSON source with its normalized JSON representation during migration.

Common mistakes to avoid

  • Expecting comments in the JSON output

    Standard JSON has no comment syntax, so HJSON comments are intentionally discarded.

  • Treating arbitrary JavaScript as HJSON

    HJSON is a data format, not a JavaScript evaluator. Expressions and functions are not supported.

  • Overwriting the only annotated copy

    Keep the original HJSON when human notes matter; the strict JSON output cannot preserve them.

FAQ

What is the difference between HJSON and JSON?

HJSON adds human-friendly syntax such as comments and optional quotes while JSON uses a stricter interchange grammar.

Does conversion run locally?

Yes. The HJSON text is parsed in your browser.

Will key order be preserved?

Parsed object order is generally retained, but consumers should not rely on JSON object key order for meaning.
