Critical Engineering Disclaimer

Data Integrity Warning. This tool runs entirely in your browser, but be aware of JavaScript limitations:

64-bit Integers: Standard JS `JSON.parse` treats numbers as IEEE 754 doubles. Integers larger than 2⁵³-1 (e.g. some Database IDs, Twitter Snowflakes) will lose precision.
Privacy: While this does not upload data, avoid pasting production credentials or PII into any web-based clipboard.
BigInt: Native JSON spec does not support BigInt literals (e.g. `123n`). They will cause parse errors.
