Can I compare specific sheets within an Excel workbook?

Yes, you can specify the exact sheet name for both the left and right inputs to compare specific tabs within your XLSX files.

What are key columns used for?

Key columns act as unique identifiers (like an ID or SKU) to align rows between the two datasets, ensuring accurate comparison even if the row order has changed.

What formats are supported for comparison?

The tool supports raw CSV text input, as well as uploaded CSV and Excel (XLSX/XLS) files up to 20MB in size.

Can I ignore formatting changes and only compare data values?

Yes, you can set the Compare Mode to 'Cell Content Only' to ignore differences in fonts, colors, or data types.

What does the exported PDF report contain?

The PDF report provides a color-coded summary of the differences, highlighting added rows, deleted rows, and specifically modified cells.
