About this flow
Validate strict JSON, format it readably, then optionally sort object keys and minify the downloaded document. Choose explicit settings, review the real downloaded output and keep your original for retry.
Limitations
- Strict JSON only: duplicate keys, malformed UTF-8, invalid Unicode, leading zeros and excess depth/size reject. Exact number tokens are preserved without JavaScript number rounding. Up to 5 MiB per input/intermediate/output, 40 nesting levels and 200,000 values. Formatting can exceed the next-step size limit; the source remains available for retry. No JSONPath precision conversion.
