Frequently Asked Questions

Why do I see garbled characters like ’ in my CSV?

These characters appear when a CSV file saved in Windows-1252 or Latin-1 encoding is opened as UTF-8. Structra detects the actual encoding and converts it to UTF-8 automatically.

How do I convert a Windows-1252 CSV to UTF-8?

Upload your file to Structra. We detect Windows-1252 encoding automatically and convert every character to UTF-8. Download the clean file — no configuration required.

Can you fix a CSV with mixed encodings?

Structra analyzes the file byte-by-byte to detect the dominant encoding and converts the entire file. Truly mixed encodings (different per row) are flagged for manual review with suggested fixes.
