Imagine this: you’re managing a sprawling Excel spreadsheet with thousands of rows of data. You need to identify high-priority tasks, flag anomalies, or categorize entries based on specific rules.

Build flexible Excel functions that automatically handle blanks, defaults, and overrides without messy nested IFs.

Replace legacy formulas with MAP, BYROW, BYCOL, SCAN, and REDUCE to build secure, scalable, and automated spreadsheets.
