LCase - VBScript

Overview

The LCase command converts all characters in a string to lowercase. It is useful for ensuring consistent data formatting, comparing strings in a case-insensitive manner, and manipulating text for readability purposes.

Syntax

LCase(string)

Parameters:

• string: The string to convert to lowercase.

Options/Flags

None

Examples

Simple Conversion:

MsgBox LCase("Hello World")

Output: “hello world”

Case-Insensitive Comparison:

If LCase("apples") = LCase("APPLES") Then
    MsgBox "Strings are equal (case-insensitive)"
End If

Common Issues

• Make sure the input string is within the allowed character limit. Extremely long strings may result in errors.

Integration

Concatenation with UCase: Convert a string to lowercase and then concatenate it with an uppercase string:

Dim combined = LCase("Hello") & " " & UCase("World")

Result: “hello WORLD”

Comparison with InStr: Perform a case-insensitive search using the InStr function:

If InStr(1, LCase("My Text"), "find this") > 0 Then
    MsgBox "String contains the search term (case-insensitive)"
End If
