How it works

Paste any messy CSV or table data — from spreadsheets, PDFs, emails, or AI tools. The cleaner auto-detects the delimiter (comma, tab, pipe, semicolon), normalizes it to standard comma-separated format, trims whitespace, removes empty and duplicate rows, and outputs clean CSV ready for import.

Common use cases

  • Cleaning CSV data copied from emails or PDFs
  • Normalizing tab-separated spreadsheet data to CSV
  • Removing empty or duplicate rows from exported data
  • Preparing data for database import or API upload
  • Cleaning AI-generated CSV or table output
// FAQ
What types of CSV issues does this tool fix?
It fixes common CSV problems: extra spaces around cells, empty rows, duplicate rows, inconsistent delimiters (tabs, pipes, semicolons), and smart quotes. It auto-detects the delimiter and normalizes everything to clean comma-separated output.
Does this support quoted CSV values?
Basic support. This tool works best for simple CSV and pasted table data. Complex quoted CSV with embedded commas, newlines, or escaped quotes may need manual review in a spreadsheet application.
Can I paste from Excel or Google Sheets?
Yes! Copy cells from Excel or Google Sheets and paste them here. Spreadsheet data is typically tab-separated when copied, and the tool auto-detects this and converts it to clean CSV.
Is my data uploaded anywhere?
No. All processing happens locally in your browser. Your CSV data never leaves your device — the same privacy guarantee as all CleanTextKit tools.
