What the CSV encoding fixer does
It repairs text that was saved in one character encoding and opened in another. "José" becomes José, "Müller" becomes Müller and "don’t" becomes don't. It detects the encoding the file was read in, reverses the damage cell by cell, and saves the result as UTF-8.
The file is repaired in your browser and never uploaded.
How to read the result
The preview shows the cells that changed, before and after. A count tells you how many cells were repaired. Cells with the replacement character, a question mark in a diamond, are left as they are, because the original letter was lost when the file was saved and cannot be recovered from the file.
How to use it
Drop the file, check the preview on a few names you know, and download as UTF-8. To open the result in Excel without breaking it again, import it through Data > From Text/CSV and choose UTF-8 rather than double-clicking it.
For cells with the replacement character, go back to the source and export again as UTF-8.
Why it matters for cold email
A name is the most personal thing in a cold email. "Hi José," tells the reader nobody looked at the list, and it hits hardest on international lists, where accented names are the norm. Sending tools rarely catch it, because to them the broken text is just text.
