Binary to Hexadecimal

[Thiyagu8423]

I have 26byte number in one cell , can I convert it to Hexadecimal using formula in one shot

First, I assume that the cell is formatted as Text, otherwise the 104 digits of 26 bytes would try to convert to an exponential number. Next, are you still using Excel 2013? If so, I can't think of a way to get the formula in a single cell (except for a UDF). In Excel 2016, Microsoft added several base conversion functions. And with the array functions, it got even easier.

Consider:

Sheet5

Cell Formulas
Range	Formula
B2	B2	=CONCAT(BIN2HEX(MID(A2,SEQUENCE(LEN(A2)/4,,,4),4)))
B4:B29	B4	=B3&VLOOKUP(MID(A$2,ROWS(A$4:A4)*4-3,4),$E$2:$F$17,2,0)

The B2 formula is a single cell formula, but it requires the newer functions. For 2013, the best I could do was the series of functions in B4:B29, with B29 being the final answer. You could put the intermediate formulas horizontally in hidden columns, and only show the final result. Or if you're willing to use VBA, I could write a UDF (User-Defined Function) that would work in 2013 and only require a single cell.
