Why These Tiny Tools Matter
APIs speak JSON. Tokens, images, and config snippets often travel as Base64. When something breaks at 11 p.m., a formatter and decoder save time before you dig into network logs.
JSON Formatting Basics
Pretty-printing adds indentation so nested objects are readable. Minifying removes whitespace for smaller payloads. Validation catches missing commas, trailing commas, and unquoted keys.
Typical Workflow
- Paste a response into JSON Formatter.
- Format to inspect structure.
- Fix errors highlighted by the parser.
- Minify again before pasting back into a request body if needed.
Base64 Without the Myths
Base64 is encoding, not encryption. Anyone can decode it. Use it to embed binary-safe text (for example, small icons in CSS or JSON), not to hide secrets.
Encode / Decode Safely
- Open Base64 Encode/Decode.
- Encode text or decode a string from an API.
- Never paste production passwords or private keys into random websites — prefer local or trusted tools for sensitive material.
Checksums With Hashes
When you download a file and the publisher lists an SHA-256 checksum, generate a hash of your copy and compare. ConvertMastery’s Hash Generator supports common algorithms for quick checks.
