HOW TO
How to use CSV Cleaner
Prepare data before importing it into a CRM, database, or dashboard.

Process it to trim cell whitespace and remove empty and exact duplicate rows.
- 3
Inspect the retained records and download the cleaned CSV before importing it elsewhere.
INPUT AND OUTPUT
Deduplicate whole records after trimming their cells
Rows containing Tea and a space-padded Tea become equal when their other values also match. A row with the same name but a different code remains a separate record.
This is not deduplication by a selected ID column, fuzzy name matching or data validation. Capitalization differences can remain distinct. Compare the cleaned data with your business rules before removing the source export.
FAQ
Common questions
Are my files uploaded?+
No. This tool processes files in browser memory on your device.
Is the tool free?+
Yes. Core processing is free, requires no account, and adds no watermark.
Does CSV Cleaner merge records with the same name?+
Only when the complete trimmed rows match. Records sharing a name but containing different IDs or other values remain distinct.
Will cleaning standardize dates or fix misspellings?+
No. It trims whitespace and removes empty or exact duplicate rows; it does not infer the intended meaning of a value.
