Format ACF Number Fields Plugin

Working with Advanced Custom Fields (ACF) is one of the easiest ways to manage custom data in WordPress. However, if you are using number fields, large numbers appear as a continuous string of digits, which isn’t very user-friendly.

That’s where this free ACF number formatter WordPress plugin comes in. It automatically formats ACF number fields with thousand separators using PHP’s native number_format() function.

Instead of showing 1000000, your site will display 1,000,000 – instantly making your data cleaner and more professional.
