Sort JSON Files Online
Sort JSON files by any column, ascending or descending, directly in your browser.
About this tool
Sort JSON files by any column — ascending or descending — directly in your browser. Add multiple sort keys for tie-breaking. Your data never leaves your device.
Frequently Asked Questions
Can I sort a JSON file by multiple columns?
Yes. Add multiple sort keys and choose ascending or descending for each. The sort is applied in the order you add the columns — the first column is the primary sort key.
Does sorting a JSON file work correctly on numbers and dates?
Yes. Numeric columns sort numerically rather than alphabetically, so 10 comes after 9. Date and timestamp columns sort chronologically when the format is recognised automatically.
Is there a row limit for sorting JSON files?
There is no row limit. Sorting happens entirely in your browser memory — files up to the available RAM on your device work fine.
Is my data private?
Yes — completely. Your file is never uploaded to any server. Everything runs locally in your browser using WebAssembly — processing happens entirely inside your tab. Once you close the tab, nothing is retained.
What is the maximum file size?
The free limit is 50 MB. For larger files, performance depends on your device's available memory — most modern machines handle 500 MB to 1 GB comfortably.
