About CSV Cleaner
A focused website for one practical task.
Purpose
Paste CSV text to normalize whitespace and deduplicate repeated rows. This lightweight tool handles common quoted fields but is not a full spreadsheet parser.
The tool is intended to work without accounts. In this starter version, calculations run in the browser and there is no form-submission backend.
Accuracy and limitations
This does not evaluate formulas, infer data types, or repair every malformed CSV file.
Formulas and assumptions are shown so visitors can review the result; no particular outcome is guaranteed.
