I appreciate you for raising this concern here, @fortvalleyproper.
Importing your bank transactions via CSV file has been challenging on your end. Let me help you fix this and achieve your goal.
Before anything else, I'd like to know the exact error message shown on your end.
The truncated import works because the maximum file size QuickBooks Online (QBO) can receive is 350 KB. Feel free to read this article for more info: Review the file format and size.
However, if your CSV file size is 350 KB below and some bank transactions are skipped, let's try using another file to ensure that the file isn't corrupted. If it doesn't work, utilize a private browser and repeat the process of using another file.
You can use these shortcut keys:
- Google Chrome: press Ctrl + Shift + N
- Mozilla Firefox: press Ctrl + Shift + P
- Microsoft Edge: press Ctrl + Shift + N
- Safari: press Command + Shift + N
If the issue persists, I recommend contacting the QBO Care Team to isolate this issue and find a resolution.
