Text before
Syntax:¶
TEXTBEFORE(text, delimiter, [instance_num], [match_mode], [if_not_found])
- text: The text string you want to search within.
- delimiter: The text or character(s) before which you want to extract the text.
- instance_num: (Optional) Specifies which occurrence of the delimiter to use. Defaults to
1. Negative numbers count from the end. - match_mode: (Optional) Can be set to
0(default) for case-sensitive matching or1for case-insensitive matching. - if_not_found: (Optional) Specifies the value to return if the delimiter is not found. Defaults to a
#N/Aerror.
Description:¶
The TEXTBEFORE function in Excel extracts the portion of a text string that appears before a specified delimiter. It
is useful for scenarios like extracting usernames from email addresses, isolating labels before a special character, or
working with structured text data.
This versatile function simplifies text processing by enabling automated extraction of text segments based on specified delimiters.
Examples:¶
-
=TEXTBEFORE("username@domain.com", "@")
Result: Returns"username"(text before the@symbol). -
=TEXTBEFORE("1-2-3-4-5", "-", 3)
Result: Returns"1-2". (Stops at the third occurrence of the delimiter.) -
=TEXTBEFORE("fruit:apple|fruit:banana|fruit:cherry", "|", -1)
Result: Returns"fruit:banana"(matches the text before the last occurrence of the delimiter). -
=TEXTBEFORE("HELLO|WORLD|EXCEL", "|", 2)
Result: Returns"HELLO"(text before the second|). -
=TEXTBEFORE("data.split.example", ".", , , "Not Found")
Result: Returns"data.split"(text before the first.). If no delimiter is found, it would return"Not Found".
Notes:¶
- Negative values for instance_num allow working backward from the end of the string to find text before a previous delimiter occurrence.
- Use the if_not_found parameter to provide custom fallback values for cases where the specified delimiter doesn't exist in the string.
- The match_mode parameter is particularly helpful when dealing with case-sensitive or case-insensitive scenarios.
- Combining
TEXTBEFOREwith other text functions, likeTEXTAFTERorTEXTSPLIT, can achieve more complex text parsing and manipulation tasks.
