Frequently Asked Questions
No. ToolZeno operates 100% client-side in your web browser. All parsing, validation, and structural comparisons happen in your local device memory. Your data is never sent to our servers, assuring absolute privacy for API payloads, database rows, or application configurations.
Yes, absolutely. By default, the 'Ignore Property Order' option is enabled. This treats objects with the same keys but different orderings (e.g. `{'a': 1, 'b': 2}` vs `{'b': 2, 'a': 1}`) as identical. If you disable this option, order discrepancies will be reported as structural modifications.
ToolZeno supports comparing files up to 10MB in browser memory. Monaco Editor's high-performance diffing engine ensures smooth side-by-side rendering, though speeds may vary based on your local device's CPU and memory.
For every difference detected, our diff engine displays its precise path using standard JavaScript object notation (e.g. `users[0].address.city` or `items[3]`). This helps you quickly locate changes in complex, deep schemas.
