I have a job interview coming up, and I've been told to brush up on using Visual Basic Applications in Excel. That would be fine, but I have no experience with the BASIC language. On top of this, my trial period for Microsoft office (2013) has expired, and I can't use Excel anymore. If at all possible, I would rather not spend €100 on an Office license for just one feature.
Are there any free alternatives to Excel that provide a spreadsheet like environment and allow for VBA programming?
