Frequently asked questions
- What statistics are shown?
- Total keys, a breakdown of value types, array lengths, object counts, and maximum nesting depth.
- How is this different from the Size Analyzer?
- Stats focuses on structure and shape; the Size Analyzer focuses on bytes and payload weight.
- Is my data uploaded to a server?
- No. Every tool on JSONPost runs entirely in your browser using JavaScript. Your JSON never leaves your device, so it is safe to use with private or sensitive data.
