Format and Validate JSON
Make ugly JSON strings readable and check for errors.
JSON Crack
Visualize JSON as a graph.
Revolutionary visualization. Turns data into interactive charts.
Why I picked this:
JSON Crack is my go-to because it completely changes how I understand complex JSON structures. Instead of scrolling through nested objects, I can see the entire data structure as an interactive graph. This has saved me hours when debugging API responses or understanding configuration files. The visualization makes relationships between data points immediately clear, which is invaluable for complex nested structures.
VS Code (Local)
Right-click > Format.
Don't paste sensitive data online. Use your editor's built-in formatter.
JSONLint
The OG validator.
Strict validation. It tells you exactly where the syntax error is.
