How to use OCT2HEX function in Excel?

The `OCT2HEX` function in Excel is used to convert an octal (base-8) number to a hexadecimal (base-16) number. Here’s how you can use this function:

OCT2HEX(number, [places])

number: This is the octal number you want to convert to hexadecimal. It should be a valid octal number, and it can be entered as text or as a numeric value.
places (optional): This is an optional argument that specifies the number of characters to use in the hexadecimal result. If the result requires more characters than specified, Excel will return an error. If this argument is omitted, the function will use the minimum number of characters needed.

Open Excel: Start Excel and open a workbook where you want to perform your conversion.
Select a Cell: Click on the cell where you want the hexadecimal result to be displayed.
Enter the Function:

Type `=OCT2HEX(`
Enter the octal number directly into the formula, or refer to a cell where the octal number is located, e.g., `A1`.
If desired, add the `places` argument to specify the length of the hexadecimal result.
Close the parentheses and press Enter.

     =OCT2HEX(17)

     =OCT2HEX(17, 3)

     =OCT2HEX(B2)

If you have an octal number `17` and want to convert it directly, you would enter:
This should return `F` because 17 in octal is equivalent to 15 in decimal, which is `F` in hexadecimal.

To convert the same octal number `17` but ensure the result has at least 3 characters, you would use:
This would return `00F`.

Valid Range: The maximum positive octal number you can use is `7777777000`, and the minimum is `-4000000000`.
Negative Numbers: If you enter a negative number, it must be a valid 10-character octal number, and Excel will process it using two’s complement notation.
Non-Octal Inputs: Make sure your input is a valid octal number. Non-octal digits will result in an error.

By following these instructions, you can easily convert octal numbers to hexadecimal using the `OCT2HEX` function in Excel.
