How can I set to see only USD in my Expenses? The Euro currency should be shown in USD.

Let me guide you on how you can set only USD in your expenses before exporting it to a CSV file, 9130. I'll also provide more details on this.

In QuickBooks Online (QBO), the Multicurrency feature allows you to pay and get paid in the foreign currencies of customers, vendors, or bank accounts that don't use your home currency. Once it's on, you can no longer turn it off. Also, Multicurrency isn't available for Simple Start users. You can upgrade your subscription to make use of this.

For further details about Multicurrency, check out this link: Set up and use Multicurrency in QuickBooks Online.

Here's how you can enable this functionality to convert any Euro currency transaction to USD (If you prefer, you can also manually set your exchange rate.) :

1. Go to Settings, then select Account and settings.
2. Click Advanced. Then, in the Currency section, tap Edit.
3. From the Home Currency dropdown, select USD.
4. Tick the Multicurrency checkbox and confirm that you understand that you can't undo this option.
5. Hit Save.

Then, to add your Euro currency, follow the steps below:

1. Go to Settings and click Currencies.
2. Select Add currency.
3. Choose the Euro currency from the Add Currency dropdown menu.
4. Hit Add.

After doing so, Only USD currency will display when you generate an Expense by Vendor Summary report. I'll add visual references below.
