Numbers without Thousand Separator when Decimal Places set to 0

Hello Looker Studio Community,

I’m encountering an issue where numbers in my tables are not displaying thousand separators when I set the “Decimal precision” to 0 in the field’s formatting.

For example, instead of seeing “1,234,567”, I see “1234567”. This makes it significantly harder to read larger numbers.

This issue only seems to occur when the decimal places are set to 0. If I have any decimal places (even if the values are whole numbers), the thousand separators appear correctly.

Has anyone else experienced this, or does anyone know of a setting or workaround to display thousand separators for whole numbers when the decimal places are set to 0?

Any help would be greatly appreciated!

Thank you.

Hello, what is your metric data type in Looker Studio? I think it automatically applies “thousand separators.”

Check my reference below:

Here is my Raw Data:

I have the same settings as you, and it does not work.

I started with a new, blank report, and it works. I guess I will delete the old report and start from the beginning.

I figured out what the issue was. When I change the decimal places, the formatting goes to “None”. So, each time I change decimal places, I need to set the formatting again.
