REGEXEXTRACT function

PRO

The REGEXEXTRACT function in Jspreadsheet Formulas Pro is a powerful tool that allows you to extract specific parts of a text based on a given pattern, known as a regular expression. This function is especially useful when you need to sift through large amounts of text and pull out certain pieces of information. For example, you could use it to extract all email addresses from a long document. The REGEXEXTRACT function makes this process much more efficient and accurate by automating it.

Documentation

Extracts parts of a text using a regular expression.

Syntax

REGEXEXTRACT(text, regex)

Parameter	Description
`text`	Text from which the parts will be extracted.
`regex`	Regular expression that dictates which parts should be extracted.

Behavior

The REGEXEXTRACT function is used to extract matching substrings according to a regular expression. Here's how it handles different types of data:

Empty cells: If a cell is empty, REGEXEXTRACT will return an empty string.
Text: REGEXEXTRACT operates on text strings. The function will match the regular expression against the text and return the first matching substring.
Numbers: If a number is passed, it will be treated as a text string and REGEXEXTRACT will try to match the regular expression against it.
Booleans: Booleans are converted to their text representations ('TRUE' or 'FALSE') and then REGEXEXTRACT will try to match the regular expression against these.
Errors: If REGEXEXTRACT cannot find a match or if the regular expression is invalid, it will return a #N/A error.

Common Errors

Error	Description
#VALUE!	This error is returned when the given regular expression is invalid.
#N/A	This error is returned when `REGEXEXTRACT` cannot find a match.
#ERROR!	Returned when the function is called with missing arguments or an invalid number of parameters.

Best practices

Always ensure that the regular expression is valid and correctly formatted to avoid #VALUE! errors.

Remember that REGEXEXTRACT will return the first match it finds. If you want to extract all matches, you may need to use an array formula or script.

Be aware that REGEXEXTRACT is case sensitive. If you need to perform a case insensitive extraction, make sure to adjust your regular expression accordingly.

Check your data type. If you want to extract data from numbers or booleans, make sure they are converted to text beforehand.

Usage

A few examples using the REGEXEXTRACT function.

// Extract a decimal number from a string
REGEXEXTRACT("The price today is $826.25", "[0-9]+\\.[0-9]+") 
returns "826.25"

// Extract the first email from a sentence
REGEXEXTRACT("Contact us at [email protected] for help", "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}") 
returns "[email protected]"

// Extract a year from a date string
REGEXEXTRACT("Release date: 2025-08-21", "\\d{4}") 
returns "2025"
