What Type of Regex Does Data Studio Use?


Scott Campbell

When it comes to working with data in Google Data Studio, regular expressions (regex) can be a powerful tool. Regex allows you to search, match, and manipulate text patterns in your data. However, it’s important to understand what type of regex syntax Data Studio uses to ensure that your expressions are compatible and produce accurate results.

What is Regex?

Regex is a sequence of characters that forms a search pattern. It is widely used in programming languages and tools for pattern matching and text manipulation. With regex, you can perform complex searches by specifying a set of rules or patterns that define the desired text sequence.

Regex Syntax in Data Studio

Data Studio uses the JavaScript regex syntax for its calculations and filtering options. JavaScript regex provides a rich set of features and operators that allow you to create precise patterns for matching and extracting data.

Character Classes

In JavaScript regex, character classes allow you to define sets of characters that you want to match. For example:

  • [a-z] matches any lowercase letter from ‘a’ to ‘z’.
  • [0-9] matches any digit from ‘0’ to ‘9’.


Quantifiers define how many times a character or group should appear in the input text. Some commonly used quantifiers are:

  • *: Matches zero or more occurrences of the preceding character or group.
  • +: Matches one or more occurrences of the preceding character or group.
  • ?: Matches zero or one occurrence of the preceding character or group.


Anchors are used to match patterns at specific positions in the input text. Two commonly used anchors are:

  • ^: Matches the start of a line.
  • $: Matches the end of a line.


Modifiers are used to perform case-insensitive or global searches. Some commonly used modifiers are:

  • i: Performs case-insensitive matching.
  • g: Performs a global search (matches all occurrences).

Using Regex in Data Studio Calculations

In Data Studio, you can use regex in calculated fields to transform and manipulate your data. For example, you can extract specific parts of a string, replace certain characters, or validate input formats.

To use regex in a calculated field, you need to enclose your expression within forward slashes (/). For example:


This expression will match one or more digits in the input text.


Understanding the regex syntax that Data Studio uses is crucial for effectively working with data and creating powerful calculations. By utilizing character classes, quantifiers, anchors, and modifiers, you can create complex patterns that accurately match and manipulate your data.
