Currencies are formatted differently in different countries and languages.
For example; $12.50 shows the currency symbol and the currency value, and in some regions it also shows the ISO code (USD in this example) as follows $12.50 USD.
With the currency format feature you can adjust the format of any currency to fit your needs as follows:
1) Workspace currency format
Note: Workspace localization preferences are set as default and used on anything shared publicly or sent to someone who does not have an account. Those preferences won't be reflected on your account, to set your own preferences follow the steps in the section 2) Account currency format below this section.
To set the workspace currency format:
Go to Settings.
Click on Workspace details.
Scroll down to Workspace localization and update the format from the Currency format option.
2) Account currency format
The workspace currency format will be reflected everywhere by default, unless overridden on an account level as follows:
Go to Settings
Click My account
Scroll down to Account localization and update your preferred Currency format.
