Nice. In older versions of xlsx they used a weird hash function with tiny hash space that could be brute-forced in <1s. There were some VBA code snippets circulating and in my old team where we had to deal with a lot of such files we all had a script as a shortcut in the Excel toolbar. I knew about the xml trick, but I could never get it to work consistently. This looks useful, thanks for sharing. |
