JSON Guides
Practical, example-driven guides for working with JSON — each one links back to the relevant tool.
- Common JSON Errors (and How to Fix Them)
The JSON syntax mistakes that break parsers most often — trailing commas, single quotes, unquoted keys, and comments — with a fix for each.
- JSON vs YAML: What's the Difference?
How JSON and YAML compare on syntax, readability, and use case — and what actually happens to comments and structure when you convert between them.
- How to Format (Pretty-Print) JSON
How to turn minified or messy JSON into readable, indented text, when to minify it back down, and how to do both from code or the command line.
