Formatter’s Text action has several transforms that you can use to change the letter case in a string of text:

Capitalize: capitalizes the first character of every word.
Lowercase: replaces all uppercase letters with lowercase.
Title case: capitalizes the first character of every word, excluding articles, adpositions, and conjunctions.
Uppercase: replaces all lowercase letters with uppercase.

This is helpful when you need a different format in later steps in your Zap.

Example

If you want to convert the title of a blog post from title case to uppercase to use in a social media post, you can use the Uppercase transform. It’ll transform “100 Things You Can Do on Zapier” to “100 THINGS YOU CAN DO ON ZAPIER” so your title stands out to your followers.

1. Add a Formatter step

In the Zap outline, click the Action step or the plus sign + to add a new action. A dialog box will open.
In the search box, search for and select Formatter. The right sidebar will open to the Setup tab.
Click the Action event field to open the dropdown menu and select Text.
Click Continue to continue to the Configure tab.

2. Set up your transform

Click the Transform field to open the dropdown menu, then select the transform that you want the Zap to perform on your string:
- Capitalize.
- Lowercase.
- Title case.
- Uppercase.
In the Input field, manually enter the string you want to transform or map a field from a previous step.
Click Continue to continue to the Test tab.

3. Test your action

Click Test step.
- The Data out tab will display the transform output so you can confirm your string was formatted correctly.
- If the new data is not what you expect, you can adjust the transform settings and retest the step again.

Once you’ve set up your Formatter action, you can use the results in further actions in your Zap. Learn more about how to automatically convert text case in your Zaps.
