Frequently Asked Questions

Why do my CSV characters look garbled?

The file likely uses Windows-1252 (Western European) encoding rather than UTF-8. Common with older Australian bank exports and Windows-generated files. To fix: open in Windows Notepad, File → Save As → Encoding: UTF-8. Then re-upload the saved file.

What is the difference between CSV and Excel files?

CSV is plain text — just values separated by commas, viewable in any text editor. Excel (.xlsx) is a binary format with formatting, multiple sheets, and formulas. CSV is universal and more compatible for data import/export; Excel is better for analysis and presentation. Most Australian accounting software (Xero, MYOB) exports to both.
