ASC function

The ASC function in Jspreadsheet Formulas Pro is a tool used to transform full-width characters into half-width characters. Full-width characters typically take up more space than half-width ones, which are more compact. This function is especially useful when working with texts that have mixed character widths, allowing for a more uniform and neat presentation. It's a simple way to standardize your data for easier reading and analysis.

Documentation

Convert full-width characters to half-width characters.

Syntax

ASC(text)

Parameter	Description
`text`	The string containing full-width characters to be converted.

Behavior

Empty cells: Returns an empty string.
Numbers: Numbers remain unchanged.
Half-width characters: Already half-width characters are returned as-is.
Mixed text: Only full-width characters are converted, other text remains unchanged.

Error	Description
#VALUE!	Returned when the input is not text (e.g., a boolean or unsupported data type).

Usage

A few examples using the ASC function.

ASC("ＡＰＰＬＥ") returns "APPLE"  
ASC("ｃｏｎｖｅｒｓｉｏｎ") returns 'conversion'
