About LearnExcel.io & Bill Whitman

Our mission

LearnExcel.io exists to make Microsoft Excel genuinely approachable. We publish clear, accurate, step-by-step tutorials that take readers from their first formula to advanced data analysis, charting, pivot tables, and automation — covering both Windows and Mac, and the differences that actually trip people up. Every guide is written to answer a real question completely, so you can solve the problem in front of you and move on with your day.

Meet Bill Whitman

Bill Whitman is the editorial voice and lead author behind LearnExcel.io. Bill writes and oversees the site’s Excel tutorials, pairing a background in technology writing with hands-on, formula-by-formula testing in Excel itself. The guiding principle is simple: explain the why, not just the clicks, and verify every step in a live spreadsheet before it’s published.

Bill’s focus areas include everyday spreadsheet skills, formulas and functions (from SUMIF to XLOOKUP and the modern dynamic-array functions), data cleanup, charts, PivotTables, and the practical financial models — budgets, loan calculators, project trackers — that most people actually open Excel to build.

When a tutorial here recommends a shortcut, names a menu path, or shows a formula, it has been checked against current versions of Excel for both Windows and Mac. Where Microsoft has changed or deprecated a feature, we say so.

How we work

We take accuracy seriously because spreadsheets are where people make decisions about money, deadlines, and data. Our editorial standards — fact-checking, sourcing, corrections, and how we handle sponsored or guest content — are documented in full in our Editorial Policy. In short:

Every guide is tested. Shortcuts, syntax, and steps are verified in Excel before publishing, and updated when Microsoft changes how something works.
We fix mistakes. If you spot an error, tell us and we’ll correct it. Articles carry a “last updated” date so you know how current they are.
We write for the question. No padding — each article leads with the direct answer, then goes deeper for the readers who want the full picture.
