Text functions in Excel are essential for manipulating and analyzing text data. They allow you to extract, combine, and transform text strings in various ways. This section will cover the most commonly used text functions, providing practical examples and exercises to help you master them.

Key Text Functions

LEFT, RIGHT, and MID
LEN
TRIM
UPPER, LOWER, and PROPER
CONCATENATE (or CONCAT)
TEXTJOIN
FIND and SEARCH
REPLACE and SUBSTITUTE

LEFT, RIGHT, and MID

LEFT: Extracts a specified number of characters from the start of a text string.
RIGHT: Extracts a specified number of characters from the end of a text string.
MID: Extracts characters from the middle of a text string, starting at a specified position.

Example:

=LEFT("Excel", 2)  // Result: "Ex"
=RIGHT("Excel", 2) // Result: "el"
=MID("Excel", 2, 3) // Result: "xce"

LEN

LEN: Returns the length of a text string.

Example:

=LEN("Excel") // Result: 5

TRIM

TRIM: Removes all extra spaces from a text string, leaving only single spaces between words.

Example:

=TRIM("  Excel   is  great  ") // Result: "Excel is great"

UPPER, LOWER, and PROPER

UPPER: Converts all characters in a text string to uppercase.
LOWER: Converts all characters in a text string to lowercase.
PROPER: Capitalizes the first letter of each word in a text string.

Example:

=UPPER("Excel") // Result: "EXCEL"
=LOWER("Excel") // Result: "excel"
=PROPER("excel is great") // Result: "Excel Is Great"

CONCATENATE (or CONCAT)

CONCATENATE: Joins two or more text strings into one string. In newer versions of Excel, CONCAT is used instead of CONCATENATE.

Example:

=CONCATENATE("Excel", " ", "is", " ", "great") // Result: "Excel is great"
=CONCAT("Excel", " ", "is", " ", "great") // Result: "Excel is great"

TEXTJOIN

TEXTJOIN: Joins multiple text strings using a delimiter.

Example:

=TEXTJOIN(", ", TRUE, "Excel", "is", "great") // Result: "Excel, is, great"

FIND and SEARCH

FIND: Returns the position of a substring within a text string. It is case-sensitive.
SEARCH: Similar to FIND but is not case-sensitive.

Example:

=FIND("c", "Excel") // Result: 3
=SEARCH("C", "Excel") // Result: 3

REPLACE and SUBSTITUTE

REPLACE: Replaces part of a text string with another text string, based on the position.
SUBSTITUTE: Replaces occurrences of a specified text string with another text string.

Example:

=REPLACE("Excel", 2, 3, "123") // Result: "E123l"
=SUBSTITUTE("Excel is great", "great", "awesome") // Result: "Excel is awesome"

Practical Exercises

Exercise 1: Extracting Initials

Task: Extract the initials from the full name "John Doe".

Solution:

=LEFT("John", 1) & LEFT("Doe", 1) // Result: "JD"

Exercise 2: Formatting Phone Numbers

Task: Format the phone number "1234567890" as "(123) 456-7890".

Solution:

="(" & LEFT("1234567890", 3) & ") " & MID("1234567890", 4, 3) & "-" & RIGHT("1234567890", 4) 
// Result: "(123) 456-7890"

Exercise 3: Removing Extra Spaces

Task: Clean up the text " Hello World " to "Hello World".

Solution:

=TRIM("  Hello   World  ") // Result: "Hello World"

Exercise 4: Combining Text with Delimiters

Task: Combine the words "Excel", "is", "fun" with a space delimiter.

Solution:

=TEXTJOIN(" ", TRUE, "Excel", "is", "fun") // Result: "Excel is fun"

Exercise 5: Case Conversion

Task: Convert the text "excel is fun" to "Excel Is Fun".

Solution:

=PROPER("excel is fun") // Result: "Excel Is Fun"

Common Mistakes and Tips

Case Sensitivity: Remember that FIND is case-sensitive, while SEARCH is not.
Extra Spaces: Use TRIM to remove unwanted spaces before performing other text operations.
Concatenation: Use TEXTJOIN for more flexibility and readability when combining multiple text strings.
