About Universal CSV Cleaner

Universal CSV Cleaner is a small browser-based utility for cleaning messy CSV, TSV, and text-delimited exports before using them in spreadsheets, databases, CRMs, and import tools.

Why it exists

Many CSV exports are almost usable, but not quite clean. They may have blank rows, empty columns, duplicate headers, mixed date formats, currency symbols, or values that spreadsheet software may treat as formulas. The goal is to provide a fast cleanup step without asking users to create an account or upload file contents.

Privacy-first design

During normal use, file contents are processed locally in your browser. The tool does not need a first-party database or account system to clean your data. The public site may load third-party advertising services when ads are enabled; details are covered in the privacy policy.

What it supports

• CSV, TSV, plain text-delimited files, and `.xlsx` workbooks.
• Comma, semicolon, tab, and pipe-delimited text.
• First worksheet extraction for `.xlsx` files.
• Clean CSV export for common spreadsheet and import workflows.

What it does not claim

The cleaner does not guarantee perfect repair for every broken file, does not infer missing business meaning, and does not provide tax, legal, accounting, security, or financial advice.
