Frequently Asked Questions

What counts as an empty row?

A row is considered empty if all its cells are blank, contain only whitespace (spaces, tabs), or are null/undefined. If even one cell has content, the row is kept.

Why remove empty rows?

Empty rows can cause import errors in databases, break data analysis, inflate file sizes, and make spreadsheets harder to read. Removing them ensures clean, professional data.

Will this remove rows with partial data?

No! Only completely empty rows are removed. If a row has even one cell with content, it's preserved.

Can I undo if needed?

The tool doesn't modify your original file. Always keep a backup. After processing, compare the row counts to see how many empty rows were removed.
