Selecting blank cells and then deleting their entire rows can remove valid Excel records. A row may contain one empty field while still holding important information elsewhere. The Ablebits guide explains why that common shortcut is unsuitable for identifying completely empty rows.

Identify Completely Empty Excel Rows Before Deleting Them

Blank rows can interfere with Excel's automatic recognition of a table's boundaries, so cleaning them can still be useful. First establish whether every relevant field in a row is empty. Preserve a backup and review the selected records before deletion. The cleanup should remove unwanted empty lines while keeping partially completed records intact.
