I'm looking for a spreadsheet app that fills in a functionality hole in Google Docs, specifically the ability to have checkboxes/toggle buttons or equivalent. The only problem is I will probably only use this once or twice so I have second thoughts about spending $10 for Numbers, even though I'm pretty sure it would do what I want. Does anyone have any suggestions?
I would like to be able to import work already done in Google Docs, but I'm fine with doing a manual export/import if it saves money.
