 Today, I want to show you how you can create your own spreadsheet with my ReactOS command line interpreter that I patched with a couple of extra features. So my command line interpreter here, you can extract the files. So you have an XA, a DLL, and then the VBA code. So that's the code that we have to put into a spreadsheet. So you can open this in an editor. This is the code, and you just have to insert that in a spreadsheet. So let's launch Excel. Now you need the developer menu. So if you don't have the developer menu, go to file options, customize a ribbon, and here in the tabs, you can enable the developer tab. And when you do this, you now have a developer tab. So you select the developer tab, and you go here to visual basic. You double click sheet one, and this will create an empty sheet one. You go back to the editor. You select all the code, copy it, and we paste it here, like this. And now you come back to the spreadsheet. You go to insert, and you take this button here, under form controls, click on the button. And then we are going to insert the button here on the spreadsheet by dragging and dropping like this, OK, and this creates the button. The macro we want to assign to the button is execute shellcode, like this. And here, if we right click, we can edit the text and turn this into CMD, like this. And now we can save our spreadsheet. I'm going to save it in the old file format as a .xls, so I'm doing save as. The name is CMD. Let's put it here in the demo folder. And so we are going to use this format, like this. And now you can just launch the interpreter, like this. So as you can see, it's reactOS with my modifications. You have the DLL function, you have the info function, and you have the privilege function.
