=HEX2DEC(`number`)

When you come across hexadecimal numbers in your Excel sheets and need to convert them to decimal format, turn to the HEX2DEC function. It simplifies the process of converting hexadecimal values into their equivalent decimal representation, ensuring accuracy and ease in your calculations or data manipulation tasks involving hexadecimal numbers. This function proves to be a valuable asset for those dealing with programming languages, digital systems, or any scenario where hexadecimal values play a role in numerical operations.

## Examples ðŸ”—

Suppose you have a hexadecimal number '1A' that you need to convert to decimal. To achieve this, use the HEX2DEC function like this: =HEX2DEC('1A')

If you have a hexadecimal number stored in cell A1 (e.g., 'FF'), you can convert it to decimal using: =HEX2DEC(A1)

## Notes ðŸ”—
