CHAR function

PRO BASIC

The CHAR function in Jspreadsheet Formulas Pro is a handy tool that translates a numeric value into a corresponding character. Each character (letter, number, symbol, etc.) has a unique numeric code, and the CHAR function uses these codes to output the specific character. For example, if you use CHAR(65), the function will return the letter 'A'. This can be particularly useful when you need to generate or manipulate text within your spreadsheet.

Documentation

Returns the character specified by a number.

Syntax

CHAR(num)

Parameter	Description
`num`	A number that represents a character in the character set used by your computer. This can be a number between 1 and 255, or a formula or reference to a cell containing such a number.

Behavior

The CHAR function returns a character specified by a number in the Unicode list. This function takes a single argument, which is a numeric code for the character you want to return. Below are the ways it handles different types of data:

Numbers: The function accepts a numeric value from 1 to 255, based on the ASCII character set, and returns the corresponding character. For instance, CHAR(65) returns 'A'.
Text: You cannot pass a text string to the CHAR function. It will result in an error because the function only accepts numbers.
Empty Cells: If an empty cell is referenced, the CHAR function will return an error since it needs a numeric input.
Booleans: Boolean values are not accepted as valid input in the CHAR function. If a boolean value is used, it will return an error.
Errors: If the cell referenced by the CHAR function contains an error, the function will also return an error.

Common Errors

Error	Description
#VALUE!	This error occurs when the input is non-numeric (e.g., text, boolean).
#NUM!	This error appears when the number is outside the valid range (less than 1 or greater than 255).
#REF!	This error is shown when the cell reference is invalid.

Best practices

Always ensure that the numeric input for the CHAR function is within the range of 1 to 255.

Be cautious while using the CHAR function with other functions. It may produce unexpected results if the other function does not return a number.

It's a good practice to use the CHAR function with the CODE function, as they are opposite of each other. The CODE function can return the Unicode value of the first character in a text string.

Avoid using cell references that might contain non-numeric values, as it will cause an error in the CHAR function.

Usage

A few examples using the CHAR function.

CHAR(65) returns "A"  
CHAR(97) returns "a"  
CHAR(36) returns "$"
