Conversion between data formats involves genuine trade-offs, not just translation. XML has attributes that JSON cannot express; JSON has arrays that XML represents only by convention; CSV has no types at all; YAML has comments and anchors that survive no round trip. Our tools expose these decisions as options and document their limits on each tool page, but a converted document is not automatically equivalent to its source. Verify results before using them in production.

Code generators infer types from the sample you provide. A field that happens to be null in your sample, an array that happens to be empty, or a number that happens to have no decimal part will all be typed from that single observation. Review generated models against your actual API contract, and treat them as a fast starting point rather than a specification.

The JWT decoder decodes token content only. It does not verify the signature or the authenticity of a token, and a successfully decoded payload proves nothing about whether the token is genuine or trustworthy. Signature verification requires the issuer’s key and must be performed by your own server.

Do not paste production tokens into this or any other online tool. Treat a JWT as you would a password.

The hash generator produces digests for integrity checking. Hashing is not encryption, and general-purpose hashes are unsuitable for password storage. The HTML encoder helps content display correctly; correct output encoding in your own application remains your responsibility. Base64 is an encoding, not a cipher, and protects nothing.
