Clean a CSV by trimming spaces, removing empty rows, and optionally deduplicating rows.

✓ Free to use
⚡ Queue-powered
🔒 Privacy-first

How it works

1

Upload your CSV file

Select the CSV that needs cleaning. Works with exports from any database, CRM, spreadsheet tool, or scraper.

2

Whitespace is trimmed from every cell

Leading and trailing spaces are removed from every cell value in every row. This prevents join failures and formatting issues on import.

3

Empty rows and duplicates are removed

Rows where all cells are empty or whitespace-only are dropped. Then rows identical across all columns are deduplicated, keeping the first occurrence.

❓ Frequently asked questions 4 answers

Three operations are applied: (1) leading and trailing whitespace is trimmed from every cell value, (2) rows where all cells are empty or whitespace-only are removed, and (3) rows with identical values in every column are deduplicated, keeping the first occurrence.

No. Only leading and trailing whitespace is removed from cell values. All other characters, the column structure, and the header row are preserved exactly.

When two or more rows have identical values in every column, the first occurrence is kept and subsequent duplicates are removed. Row order in the output follows the original file.

Currently deduplication compares all columns. Column-specific deduplication — for example, removing rows with a duplicate email address regardless of other fields — is not yet available.
