Selecting cells with specific conditions

I am having trouble finding a function that will allow me to select cells that meet certain conditions across an entire sheet instead of just a row or column. I have an identity matrix with cells that contain numeric values that range from 0-1 and I need to select all the cells which contain a value greater that or equal to .975

Autofilter can accomplish this task, but only for one column at at time. As I routinely need to check matrices with 50+ columns, I need a quicker solution. I think I could do this with Visual Basic, but I have little programming experience. Could anyone help me out?

I want to highlight those cells. Sorry for the confusion. Basically I need to bold all the cells that are greater than .975 in value. After that I have to cross reference all the bolded cells in a column with their respective file names. I will attach a file, which contains some of the information I have to work with. I realize that someone with the proper training could automate the entire process, but I sadly lack that skill. The filenames are listed in column A and the rest of the data is a matrix. So column B stands for File 1A compared to every other file in the matrix

I am not sure that my last post made sense to anyone but me. Let me explain the end result I wish to obtain for those who cannot decipher my unfortunately jumbled thought process.

These numbers represent the level of similarity between the files listed in column A. I need to organize all the files into groups which all share at least .975 identity. So continuing the bolded cell method that I am currently using, all the cells in a column which are bold would be grouped.

Also since the data is in an identity matrix, only the bottom "half" or the top "half" of the data is relevant since theoretically they should be a mirror images of each other.

I hope that is clearer.

Wow that is amazing. You are awesome! Of course now that you told me how to do it, it seems like I should have known that myself. You have just saved at least 20 hours of mind numbing clicking. I hope karma is good to you.
