Learn how to use the EDATE function in Excel to add or subtract months from dates. Covers contract renewals, payment schedules, leap years, and EDATE vs EOMONTH. This is an interesting function which is helpful in multiple occasion for data analyst, finance professionals, students and teachers.
FLOOR always rounds down to the nearest multiple of your chosen significance; CEILING always rounds up. Unlike ROUNDDOWN and ROUNDUP which work in decimal places, these functions snap to any multiple — 5, 10, 0.05, 0.25, or a time interval like 15 minutes. This guide covers both functions and their .MATH variants with six practical examples covering prices, bundle quantities, time rounding, grade boundaries, and negative number handling.
TEXTJOIN replaces CONCATENATE with a single function that accepts a range, writes the delimiter once, and skips blank cells automatically with one TRUE/FALSE argument. This guide covers six practical examples — from comma-separated lists and address building through conditional joins with IF, date formatting with TEXT(), and line-break separators using CHAR(10).
WORKDAY takes a start date and a number of working days, and returns the exact deadline date — automatically skipping weekends and any holidays you provide. It is the companion to NETWORKDAYS: use NETWORKDAYS to count elapsed working days, and WORKDAY to find what date falls N working days in the future or past. This guide covers forward planning, backward planning, invoice due dates, delivery chains, WORKDAY.INTL for custom working weeks, and the workday-check formula trick.
NETWORKDAYS counts the working days between two dates, automatically skipping weekends and subtracting any public holidays you provide. It is the essential function for project timelines, payroll calculations, SLA monitoring, and monthly capacity planning. This guide covers both NETWORKDAYS and NETWORKDAYS.INTL with six practical examples — from basic counts through custom weekend definitions for global businesses.
CHOOSE is one of Excel’s most versatile and most overlooked functions — it picks a value from a list by position number, and because that number can come from a dropdown or a formula, the result changes dynamically. Unlike FILTER, SORT, and XLOOKUP, CHOOSE works in every Excel version from 2003 to 365 with no dynamic array support required. This guide covers six practical examples including scenario models, day names, VLOOKUP table switching, quarter labels, and the classic left-lookup trick.
XMATCH does everything MATCH does, but better. It defaults to exact match so you never accidentally return a wrong result, can find the last occurrence in a list, supports wildcards in a dedicated mode, and adds next-larger approximate matching that MATCH cannot do at all. This guide covers the full syntax, a direct comparison table, and six examples from basic position lookup through two-way INDEX+XMATCH and binary search on large datasets.
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.
