What this cleaner actually does

1. Parse messy exports

Detect comma, semicolon, tab, and pipe-delimited files, including common spreadsheet exports with quoted values.

2. Normalize structure

Clean headers, trim whitespace, collapse repeated spaces, remove empty rows, and make duplicate headers unique.

3. Review before download

Inspect source and cleaned previews side by side, then export both the cleaned CSV and a JSON change log.

Why use this local CSV cleaner

Use this before importing vendor exports, CRM lists, bank statements, survey results, or ecommerce orders into BI tools, spreadsheets, scripts, and reconciliation workflows.
