When working with data in Google Sheets, it’s common to encounter strings that need to be split into separate values. This can be a crucial step in data cleaning, processing, and analysis. In this blog post, we’ll explore the various ways to split a string in Google Sheets, including the built-in functions and advanced techniques.
Why Split a String in Google Sheets?
Splitting a string in Google Sheets is essential when you need to extract specific parts of a text, such as names, dates, or keywords. This process is often used in data preprocessing, data cleaning, and data analysis. For instance, you might have a column containing full names, and you want to extract the first and last names. Or, you might have a column containing dates in a specific format, and you want to extract the day, month, and year.
Splitting a string can also help you to:
- Extract specific information from a text
- Transform data into a more manageable format
- Prepare data for analysis or visualization
- Remove unwanted characters or spaces
Using Built-in Functions
Google Sheets provides several built-in functions that can help you split a string. The most commonly used functions are:
1. SPLIT Function
The SPLIT function is used to split a text string into multiple parts based on a specified delimiter. The syntax is:
SPLIT(text, delimiter)
Example:
| Text | Delimiter | Result |
|---|---|---|
| “hello,world” | , | [“hello”, “world”] |
2. REGEXEXTRACT Function
The REGEXEXTRACT function is used to extract a substring from a text string using a regular expression. The syntax is:
REGEXEXTRACT(text, regex)
Example:
| Text | Regex | Result |
|---|---|---|
| “hello-world” | “-([a-z]+)” | “world” |
3. REGEXREPLACE Function
The REGEXREPLACE function is used to replace a substring in a text string using a regular expression. The syntax is: (See Also: How to Google Sheets? Master Spreadsheet Skills)
REGEXREPLACE(text, regex, replacement)
Example:
| Text | Regex | Replacement | Result |
|---|---|---|---|
| “hello-world” | “-([a-z]+)” | ” “ | “hello world” |
Advanced Techniques
In addition to the built-in functions, there are several advanced techniques you can use to split a string in Google Sheets. These techniques involve using formulas, arrays, and regular expressions.
1. Using Formulas
You can use formulas to split a string by using the SPLIT function in combination with other functions, such as the INDEX and MATCH functions. For example:
=INDEX(SPLIT(A1,"-"),MATCH(1,REGEXEXTRACT(A1,"-"),0))
This formula splits the text in cell A1 using the “-” delimiter, and then uses the INDEX and MATCH functions to extract the second part of the split text.
2. Using Arrays
You can use arrays to split a string by using the SPLIT function in combination with the ARRAYFORMULA function. For example:
=ARRAYFORMULA(SPLIT(A1,"-"))
This formula splits the text in cell A1 using the “-” delimiter, and then returns an array of the split text.
3. Using Regular Expressions
You can use regular expressions to split a string by using the REGEXEXTRACT function in combination with other functions, such as the REGEXREPLACE function. For example: (See Also: How to Add Gantt Chart in Google Sheets? Effortlessly Organized)
=REGEXREPLACE(A1,"-([a-z]+)"," ")
This formula uses the REGEXREPLACE function to replace the “-” delimiter with a space, and then returns the modified text.
Conclusion
Splitting a string in Google Sheets is a powerful technique that can help you to extract specific information from a text, transform data into a more manageable format, and prepare data for analysis or visualization. By using the built-in functions and advanced techniques discussed in this blog post, you can split strings in a variety of ways, including using delimiters, regular expressions, and formulas.

FAQs
What is the difference between the SPLIT and REGEXEXTRACT functions?
The SPLIT function is used to split a text string into multiple parts based on a specified delimiter, while the REGEXEXTRACT function is used to extract a substring from a text string using a regular expression.
How do I split a string using a regular expression?
You can use the REGEXEXTRACT function to split a string using a regular expression. For example:
=REGEXEXTRACT(A1,"-([a-z]+)")
This formula uses the REGEXEXTRACT function to extract the substring that matches the regular expression “-([a-z]+)” from the text in cell A1.
Can I use the SPLIT function with an array formula?
Yes, you can use the SPLIT function with an array formula. For example:
=ARRAYFORMULA(SPLIT(A1,"-"))
This formula uses the SPLIT function to split the text in cell A1 using the “-” delimiter, and then returns an array of the split text.
How do I split a string using a formula?
You can use formulas to split a string by using the SPLIT function in combination with other functions, such as the INDEX and MATCH functions. For example:
=INDEX(SPLIT(A1,"-"),MATCH(1,REGEXEXTRACT(A1,"-"),0))
This formula splits the text in cell A1 using the “-” delimiter, and then uses the INDEX and MATCH functions to extract the second part of the split text.
Can I use the REGEXREPLACE function to split a string?
Yes, you can use the REGEXREPLACE function to split a string. For example:
=REGEXREPLACE(A1,"-([a-z]+)"," ")
This formula uses the REGEXREPLACE function to replace the “-” delimiter with a space, and then returns the modified text.
