Questions & answers

Is the running difference a cumulative subtraction?

No. It is the current input minus the preceding input; the first row has no predecessor.

Will CSV keep all large digits in Excel?

The file contains all digits, but spreadsheets may infer numeric types and round them. Import those columns as text or use the JSON export, which stores large integers as strings.

Can I save and reopen my settings?

Yes. Save project downloads a JSON file for this tool. Open project restores it; undo and redo work during the current session.

Does the table contain every result?

The table is paginated in groups of 50. Downloads contain all listed rows. The partition tool intentionally caps its example listing while reporting the full exact count.
