Lower-Casing Extension

Prerequisites

• utag v4.38 or later. For more information about updating the utag.js template, see our knowledge base article Best Practices for Updating to the Latest Version of utag.js.
• About Extensions.

How it works

This extension uses the JavaScript method String.toLowerCase() to convert data layer values to lower-case. The extension can be applied to all data layer variables or specific ones.

Using the extension

Once the extension is added, the following configuration options are available:

• All Variables to Lower Case: (Default: Yes)
  • Yes (default): sets all variables to lower-case.
  • No: only set specific variables to lower-case.

Select a variable from the drop-down.
Click the + button to add more variables, or the - button to remove variables.

Example

In this example, lower-casing is performed on a specific variable, search_keyword. This is a common practice to ensure that that all tracked searches are case-insensitive.

Step to configure:

1. Add the Lower-Casing extension.
2. Set a title.
3. Set All Variables to Lower Case to No.
4. From the variable drop-down, select Search Keyword.
