Format JSON and compute integrity checksum
After formatting JSON for comparison or review, the computed checksum serves as a lightweight integrity fingerprint. This is useful when sharing formatted configs and needing to confirm the content has not been altered.
What it solves
Pretty-print a JSON document and compute a CRC32 checksum to detect any subsequent modifications.
Input → Output
JSON Formatter input → CRC32 Checksum output across 2 steps.
