We use Excel a lot, just about every day. And just about every day, it aggravates us. But then there are the times when we figure something out, some cool way to convert numbers or perform a calculation, and Excel has redeemed itself. And so goes the love/ hate relationship. We’re constantly amazed by what it can do. Spreadsheets, templates, formulas, functions, equations, pivot tables, look-ups, charts and reports, a precious way to express our investment of time.
