Let's perform some basic troubleshooting to isolate this issue with uploading QuickBooks Online data. There are times when a browser's cache becomes full or damaged. When this happens, issues like this can occur.

First, log in to your QBO account using an incognito or private browser. Since this doesn't store data in the cache, it the best place to isolate browser issues. Kindly use either of the following shortcut keys:
 

• Google Chrome, press CTRL  + Shift + N
• Mozilla Firefox: press CTRL  + Shift + P
• Internet Explorer: press CTRL  + Shift + P
• Safari: press Command + Shift + N

If you're able to upload the data successfully, you may want to clear the browsing history of your regular web browser. This will remove previously-stored browsing data that might have caused the issue. Otherwise, you can try using other supported browsers to be thorough.

I'm here to ensure you can uploading csv format files in QuickBooks, @JRIVERA1.

Let me share some possible reasons why there are some errors when importing bank transactions using CSV:

• Incorrect mapping
• Inaccurate formatting

To fix this, make sure you have chosen the correct columns in the mapping stage. QuickBooks will not be able to read the data otherwise. 

Here's how to reach them. Additionally, not all banks create their CSV files the same way, so you may need to make extra changes to get your transactions in. Then, check the format of the CSV file you got from your bank to upload transactions to QuickBooks.
