Frequently Asked Questions

Why does my Excel CSV export look broken?

Excel's CSV export frequently adds a BOM marker, uses Windows-1252 encoding instead of UTF-8, and adds CRLF line endings. These cause issues in Python, Google Sheets, and most databases. Structra fixes all of them.

How do I fix a CSV file exported from Excel?

Download the CSV from Excel, then upload it to Structra. We detect and fix all Excel-specific issues — BOM, encoding, CRLF, and special characters — and give you a clean UTF-8 file.
