Identify Variable Type
I need to check if the variable name starts with 'str' to identify it as a string.
=LEFT(A2, 3)="str" How it works: The `LEFT` function extracts a specified number of characters from the beginning of a text string. In this scenario, `LEFT(A2, 3)` extracts the first three characters from the variable name in cell A2. We then compare this extracted substring to the literal string "str" using the equality operator (`=`). If they match, the formula returns `TRUE`, indicating a string variable. Otherwise, it returns `FALSE`. This provides a quick boolean check for variable type identification.
Data Setup
| VariableName | Description |
|---|---|
| strUserName | User's full name |
| intAge | User's age |
| strAddress | User's physical address |
| boolIsActive | User's active status |
| strCity | City of residence |
Step-by-Step Guide
Assume your variable names are listed in column A, starting from cell A2.
In cell B2, enter the formula: `=LEFT(A2, 3)="str"`.
Press Enter. Cell B2 will now display `TRUE` if the variable name in A2 starts with 'str', and `FALSE` otherwise.
Drag the fill handle (the small square at the bottom-right of cell B2) down to apply the formula to the rest of your variable names in column A.
