2.2.1

What's New in Version 2.2.1 🎉

Major Enhancements

• Interleaved Row Sorting: ⭐ NEW
  Deleted rows now appear in context! When rows are deleted, they're inserted immediately before the next corresponding new row position, making it much easier to understand what changed and where.

  Example:

  • Old File: New File:

  • Row 5: Data A Row 5: Data B

  • Row 6: Data B Row 6: Data C

  • Row 7: Data C

  • Display Order (Interleaved):

  • Row 5 → 5: Data A → Data B (Modified)

  • Row 6 → -: Data B (Deleted, shown before new row 6)

  • Row 7 → 6: Data C (Matched)

• Blank Key Column Handling: ⭐ NEW
  When rows have empty key column values, the tool now intelligently matches them using:

  1. Position-based matching (same row number in both files)
  2. Content comparison (all columns must match exactly)

  This prevents false positives when comparing files with occasional blank IDs.

• Enhanced Row Matching Accuracy: ⭐ NEW

  • Fixed row number calculation for non-default header rows
  • Improved Excel row number display (correctly shows header row + data row index)
  • Better handling of edge cases in key-based matching
