Cell & Formula is run by analysts and accountants who learned spreadsheets the hard way, by breaking real reports under deadline. We teach the version of Excel that actually shows up at work.
We focus on the 20% of features that solve 80% of problems: lookups, pivot tables, clean formulas, and dashboards people can read. No 200-function firehose.
The site is free, supported by ads and our weekly newsletter. The goal is simple: make you the person colleagues turn to when a spreadsheet breaks.
