Clean a messy list by trimming whitespace, removing blank rows, collapsing repeated spaces, and deleting duplicate values.
About this tool
Use the all-in-one cleaner when a pasted list has several small quality problems at once. It combines the safe cleanup steps most exports need.
Options remain explicit so you can see exactly which normalizations will be applied before copying the result.
FAQ
