This past Wednesday I announced the release of Lookup Logic: Harnessing Excel's 17 Most Powerful Functions, and the response has been very gratifying. Dozens of professionals have already grabbed their copies, and the feedback is outstanding: I had no idea XLOOKUP could do so much. I spent an hour yesterday converting my old VLOOKUP formulas and my workbooks are cleaner, faster, and easier to maintain. This book paid for itself in the first chapter.
— Michael T., Financial Analyst The FILTER function section is a revelation. I've been manually filtering and copying data for years. Now I have dynamic reports that update automatically. Game-changer!
— Sarah K., Operations Manager I was intimidated by Dynamic Arrays, but the book explains them so clearly that I was building sophisticated formulas within an hour. The combination of UNIQUE and SORT for dropdown lists alone was worth the price.
— David R., Data Analyst Finally, a resource that focuses on modern Excel instead of rehashing the same old VLOOKUP tutorials. This is what I've been looking for.
— Jennifer L., Business Intelligence Specialist There are only a few days left to save 30% The introductory discount ends Tuesday, November 11, at 11:59 PM Pacific Time. After that, prices return to normal.
