Why Do CSV Accents Get Scrambled?
Scraped databases, CRM exports, and Microsoft Excel often use conflicting text encodings. Here is how CleanMyCSV repairs them:
1. The "é" Double-Encoding Disaster
When a UTF-8 file is opened and saved by Excel using Windows ANSI (Windows-1252) settings, single accents transform into double-byte gibberish: é becomes é, à becomes à , and ’ becomes ’. Sending cold emails with these variables ruins your response rates. CleanMyCSV decodes the raw buffer and restores human-readable text.
2. Legacy Excel ANSI & MacRoman Conversion
Older macOS exports use MacRoman encoding, while Windows software defaults to ISO-8859-1 or CP1252. CleanMyCSV tests your file against multiple encoding standards in isolated memory and forced-converts the final output to UTF-8 BOM, guaranteed to open cleanly on both Windows Excel and Mac Numbers.
3. Proper Name & International Character Protection
International names contain complex accent marks (e.g., Müller, François, Sánchez). Our engine normalizes name capitalization while protecting delicate multi-byte characters and language particles (De, Van, Von, Mc, O').
4. Zero-Risk Lead List Cleaning
Growth marketers and freelancers deal with sensitive B2B leads. We enforce a 100% ephemeral processing pipeline: your files are processed in isolated Cloud Run memory and automatically purged within 24 hours.
