My boss had created an excel spreadsheet to aid us in our network configurations. Unfortunately he’s not a very good speller. There were quite a few spelling errors that were driving me nuts, so I was going to update the template with the correct words. Unfortunately, again, he locked the spreadsheet to prevent changes to the code. And he was on vacation.<\/p>\n
So a brief google search found this gem (JSBI<\/a>), which I’ll repost here just in case it disappears.<\/p>\n Open the spreadsheet with the locked cells or sheets. Then run Macro1. This may take a while depending on the speed of the machine. It looked like excel locked up on my test system. After a minute or two the alerts pop up with the password. In my case it was “password123”. Secure? Sure.<\/p>\n","protected":false},"excerpt":{"rendered":" My boss had created an excel spreadsheet to aid us in our network configurations.
