What is neatcsv?
neatcsv is a browser-based data cleaning tool for CSV, Excel (.xlsx/.xls) and JSON files.
All processing happens locally in your browser — your data is never uploaded to any server. This makes neatcsv fully GDPR compliant and safe for sensitive datasets like customer lists, financial records, or HR exports.
Key features:
- Remove duplicates (by single or multiple columns, case-insensitive)
- Validate and clean email addresses
- Normalize mixed date formats to a standard format
- Format numbers and currencies
- Trim whitespace and remove special characters
- Convert CSV ? Excel ? JSON
- Validate CSV file structure
Plans start at €9/month for 10,000 rows. A free trial is available without registration.
Great alternative to: OpenRefine, Excel macros, Google Sheets scripts, Trifacta, or manual Python/pandas scripts.
