The SORT function creates a sorted copy of your data in a new location, leaves the original completely untouched, and updates automatically whenever the source changes. This guide covers the full syntax, the SORTBY companion function, and six practical examples — from simple A-Z lists to multi-column sorts, dynamic filtered views, and randomizing a list with RANDARRAY.
Before Excel 365, getting a distinct list from a column took complex multi-function array formulas that only experts could write. UNIQUE does it with a single formula that spills automatically, updates live, and combines effortlessly with SORT and FILTER. This guide walks through six practical examples from basic deduplication to dynamic dropdown lists powered by a spill range.
VLOOKUP is one of the most used functions in Excel — and one of the most misunderstood. This beginner-friendly guide breaks down all four arguments, walks you through writing your first formula in four steps, and covers six practical examples from product pricing to cross-sheet lookups, plus a complete error reference table.
Nested IF formulas get harder to read with every condition you add. The IFS function replaces the entire nesting structure with a flat, readable list — write each condition and its result in order, left to right, with no brackets to lose. This guide covers syntax, a direct nested IF vs IFS comparison, and six practical examples including grade scales, commission tiers, shipping rules, and compound AND conditions.
SUMPRODUCT is one of Excel’s most underestimated functions. Most users stop at multiplying two columns — but it can handle conditional sums, OR logic, weighted averages, date-based grouping, case-sensitive matches, and unique value counts, all without helper columns and in every Excel version from 2003 to 365. This guide shows you seven patterns that will change how you work with data.
VLOOKUP has been Excel’s most-used lookup function for decades — but XLOOKUP, available in Excel 365 and 2021, fixes every limitation VLOOKUP has. This guide compares them across 6 real differences including left lookup, default match type, error handling, column insertion safety, multi-column returns, and reverse search — plus a decision guide for choosing the right one.
DATEDIF is Excel’s hidden powerhouse for date calculations — it doesn’t appear in autocomplete, but it handles age, tenure, and date differences in years, months, or days with a single formula. This guide covers all 6 unit codes and 6 practical examples including full age strings, HR tenure banding, project duration, and birthday countdowns.
The Excel FILTER function replaces manual filtering entirely — one formula extracts matching rows and spills them dynamically anywhere on your sheet. This guide covers FILTER through 6 practical examples: single condition, AND/OR logic, date ranges, partial text matching, and chaining with SORT and UNIQUE. Available in Excel 365, 2024 and 2021.
INDEX MATCH is the most powerful lookup combination in Excel — and once you learn it, you rarely go back to VLOOKUP. This complete guide explains how each function works individually, shows you how to combine them, and walks through 6 practical examples covering left lookups, two-way matrix lookups, multiple-criteria matching, wildcard searches, and case-sensitive lookups.
Need to count data based on more than one condition in Excel? The COUNTIFS function lets you analyze data with precision by applying multiple criteria across ranges. In this guide, learn the COUNTIFS formula, understand how it works, and explore practical examples that help you build accurate reports and insights quickly.
Struggling with messy Excel errors like #DIV/0! or #N/A? The IFERROR function helps you clean up your spreadsheets by replacing errors with meaningful values, blanks, or custom messages. In this step-by-step guide, learn how to use IFERROR in Excel with practical examples, real use cases, and formulas that make your reports look professional and error-free.
Struggling to sum data across multiple conditions in Excel? This guide covers SUMIFS with multiple criteria through 8 practical examples — from basic text matching to date ranges, wildcard patterns, OR logic, and dynamic cell-referenced filters. Each example includes a sample dataset and a ready-to-copy formula. Perfect for beginners and intermediate Excel users building reports, dashboards, or payroll sheets.
