Mastering Number Formatting in Webflow: Overcoming the Challenge of Adding Commas

As a Webflow user, you've probably had to deal with number formatting at some point. It could be displaying prices, counts, or other numerical data on your website. But, if you've tried adding commas to your numbers for better readability, you might have hit a brick wall. It's a common challenge many face - but not to worry! We're here to help you overcome this hurdle.

The Problem

Webflow's CMS has a robust set of features for handling and displaying data. However, it doesn't natively support adding commas to numbers. This is a small but significant issue, especially when dealing with large numbers where commas are needed for better readability.

Let's take an example. You have a numeric field in your CMS that represents a price, let's say $1000. But, when you display this price on your website, you'd want it to show as $1,000, not $1000. This is where the challenge arises.

The Solution

Although Webflow doesn't allow adding text to a numeric field directly, there are workarounds to this issue. Here's a step-by-step guide on how to add commas to numbers using a bit of custom code:

Step 1: Change Field Type to Text

Webflow doesn't allow adding text to a numeric field. So, the first step is to change the field type to text. To do this, navigate to the CMS, select the collection that contains the number field, and change the field type to text.

Step 2: Add Custom Code

Next, you need to add a bit of JavaScript code to your page settings. Here's the code you need to add:


Step 3: Add ID to the Text Block

Finally, you need to add an ID of "comma" to the text block that is pulling in the number field from your CMS. To do this, select the text block, go to the settings panel, and add "comma" in the ID field.

And that's it! Now, when you publish your site, your numbers will be displayed with commas. Do note that you will only be able to view the commas on the published site, and not in the Webflow designer.

This method is not only simple but also flexible, allowing you to format numbers as needed based on the presentation layer, rather than in the data itself. So, go ahead and give it a try!

Pro Tip: Utilizing the Power of Custom Attributes for Advanced Number Formatting

While the previously discussed method is great for adding commas to your numbers, what if you need a more advanced formatting? For instance, you may want to display numbers in different formats based on specific conditions. Here's where the power of custom attributes in Webflow comes into play.

Custom attributes allow you to add additional information to an HTML element. You can use them to add a data attribute that specifies the format in which the number should be displayed. Here's how you do it:

  1. Go to the settings panel of the text block and scroll down to the Custom Attributes section.
  2. Click on the '+' button to add a new attribute.
  3. Enter 'data-format' in the Name field and the desired format in the Value field. For example, you could enter 'currency' to display the number as a currency.

Then, you can modify your JavaScript function to read this attribute and format the number accordingly. Here's an example:


This way, you can have multiple number formats on your site, all handled by the same script. It's a powerful tool, so don't be afraid to explore its potential!
