Remove completely blank Excel worksheet rows

Step-by-step approach

Verify which worksheet contains the tabular dataset.
Distinguish truly blank rows from rows with intentional whitespace.
Run the blank-row cleaner on a copy and export CSV.
Check that rows used for section separation were not needed.
Reopen the original workbook for formatting or charts.

Try the matching tool

Open XLSX Blank Row Cleaner to work on a local copy. Review the result before importing it elsewhere.

What this does not solve

Browser tools can validate known structures and transform available data, but cannot restore deleted or corrupted bytes, infer unknown business facts, or guarantee that a target system will import every field as intended.
