How to Clean a List Before Importing It into a Spreadsheet

A pasted list can look fine in a document and still break when you import it into a spreadsheet. Extra spaces, blank rows, duplicate lines and mixed separators can turn a simple list into messy data.

Start with the cleanup tools that match the problem: Remove Extra Spaces, Remove Duplicate Lines, Sort Lines A-Z and Trim Text.

Clean in small steps

Do not run every cleanup at once. First remove blank or accidental spaces, then check duplicates, then sort only if order does not matter.

Keep one item per line

Spreadsheet imports are easier when each item occupies one line. If your source mixes commas, tabs and line breaks, normalize the structure before importing.

Check a small sample first

Import ten rows before importing the whole file. If those rows split correctly, repeat the same cleanup on the full list.
