excel file to make public bitcoin address

[altcointalk14]

Hello,

Has anyone found an excel spreadsheet that you can enter your string of 256  ones & zeros and it would spit out the HEX format and the public address?

Not aware of an Excel spreadsheet to do that, but I did write a simple C program that generates addresses from a WIF private key. It would be pretty simple to modify the program to work with 256 ones & zeros instead of a WIF key

It would be tedious to write as you couldn't use numbers. Excel uses floats.

BIN2DEC() only supports 10 bits. HEX2DEC() only supports 40 bits.

even n = 115792089237316195423570985008687907852837564279074904382605163141518161494337 pasted into a cell:
1.15792089237316E+77

This guy made a spreadsheet that does SHA256 of some text, which is already impressive. It has about 80 sheets of formulas. https://bitcointalk.org/index.php?topic=809430.0
