LOWER function

PRO BASIC

The LOWER function in Jspreadsheet Formulas Pro is used to transform all uppercase letters in a given text string to lowercase. By inputting a specific text string into this function, it will return the same string but with all characters in lowercase. This is particularly useful when you need to standardize text data in your spreadsheet. It's a simple yet powerful tool to make your data more consistent and easier to analyze.

Documentation

Converts all uppercase letters in a text string to lowercase.

Syntax

LOWER(text)

Parameter	Description
`text`	The text string that you want to convert to lowercase. You can enter the text string directly into the function or reference a cell that contains the text string.

Behavior

The LOWER function is used to convert all uppercase characters in a text string to lowercase. Here are some typical behaviors:

Text: If the input is a text string, the LOWER function will convert all uppercase letters to lowercase. For example, LOWER("HELLO WORLD") will return hello world.
Empty cells: If the cell reference is empty, the LOWER function will return an empty string.
Booleans: If a boolean value (TRUE or FALSE) is given as an argument to the LOWER function, it will return the lowercase of the boolean's text representation, i.e., true or false.
Errors: If the input is an error value, the LOWER function will return the same error value.
Numbers: If the input is numeric, LOWER will return the number as it is because there are no uppercase or lowercase numbers.

Common Errors

Error	Description
#VALUE!	This error occurs when the `LOWER` function's argument is non-text (except for numbers, booleans, or error values).

Best practices

Although the LOWER function can handle numbers and booleans, it's primarily designed for text strings. It's best to use it with text for clarity and to prevent unexpected results.

Be careful when using this function with data that is case-sensitive. Converting everything to lowercase may cause data loss if the case was important.

If you're dealing with text strings with leading or trailing spaces, consider using the TRIM function before using LOWER to ensure accurate results.

If you want to capitalize the first letter of each word, use the PROPER function instead of LOWER.

Usage

A few examples using the LOWER function.

LOWER("HELLO") returns the text string "hello"  
LOWER(A1) returns the text string in cell A1 with all uppercase letters converted to lowercase  
LOWER("Hello World") returns the text string "hello world".
