Transparent methodology
What the result includes—and what it does not
Built for anyone who needs rows ordered without opening a spreadsheet app.
Calculation method
- 1Stable multi-key sort on up to two columns, ascending or descending, comparing numerically whenever both values are numbers.
- 2Stability means rows with equal keys keep their original relative order — critical for auditable outputs.
Assumptions and limits
- Sorting loads the whole table in memory: heavy above 50 MB, with ~100 MB as an approximate desktop maximum.
- File contents are processed locally and never uploaded; the only telemetry is an aggregate operation counter with no file names, column names or contents.
Worked example
Ranking by amount
Input: A 100 MB transaction log sorted by amount descending.
Output: The sorted file, biggest transactions first — about 19 seconds in our engine benchmark; browser and content can change that.
