If you try to use the Import Tool (especially the CSV Import) and the upload fails or causes the app to freeze, it may be due to how your CSV file is formatted.
Why this happens
Kiwi Sizing expects CSV files to use commas ( , ) to separate data.
Some systems, however, export CSVs using semicolons ( ; ) instead - especially in regions where commas are used as decimal separators.
When a file uses semicolons instead of commas, the app can’t read it properly, which may cause the import to fail or even make the app crash.
How to fix it
Open your CSV file in a text editor (like Notepad or VS Code) or spreadsheet tool (like Excel or Google Sheets).
Check the separators:
If you see
;between column names or values (for example:Size;Bust;Waist), change them to commas (,).
Save the file and re-upload it in the app.
💡 Tip: When exporting a CSV from Excel or another tool, make sure you select Comma ( , ) as the delimiter.
Workaround
We’ve included an example CSV file that uses the correct format.
If your import keeps failing, try using that sample as a base - just replace the data with your own measurements and re-upload.
