SEQUENCE Formula in Excel

What this does

SEQUENCE produces a run of numbers as a spilled array. Because Excel stores dates as numbers, it is also the shortest way to build a date series: starting from a date and stepping by 1 gives consecutive days, which is how a calendar column or a project timeline gets built without dragging a fill handle. Its second common use is feeding other array functions — supplying the k argument to LARGE for a top-n list, or the row indices to INDEX. A step of -1 counts down. Most people learn this as a sequence of clicks and forget it by next week; learning it as a pattern instead is what lets you apply it to the next, slightly different version of the problem without starting from scratch. That is the difference this page is trying to make. Treat “sequence formula in excel” as a small repeatable workflow rather than a one-off click you hope to remember next time. Use a small test block before the live file, so any surprise in the affected formula shows up while it is still harmless. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. That turns a workflow that saves repeating the same clicks every week into a method you can reuse, explain, and defend when the workbook leaves your screen.

A worked example

Thirty consecutive dates from a start in A1: =SEQUENCE(30, 1, A1, 1), formatted as dates. Twelve month-start dates: =EOMONTH(A1, SEQUENCE(12, 1, -1, 1))+1. A top-five list in one formula: =LARGE(B2:B500, SEQUENCE(5)). A 4×3 grid numbered 1 to 12: =SEQUENCE(4, 3). SEQUENCE replaces the drag-to-fill for any regular series, and a series that is a formula updates when its start does. One habit worth forming early: name the cells that hold your inputs, so the formula reads in plain language instead of a string of cell addresses. A reviewer — or you in three months — can then follow the logic without decoding what B7 and D2 were supposed to mean, which is most of what makes a sheet maintainable.

In Google Sheets

Google Sheets handles this almost identically to Excel. The formula syntax above is the same, and the menu lives under a slightly different label rather than a ribbon tab. Use the platform toggle at the top of the page to switch every keyboard shortcut between Windows and Mac, and expect at most cosmetic differences in naming. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. The short version of “sequence formula in excel”: the answer is at the top of this page, the tool proves it on your own numbers, and the sections above explain why it holds so the next variation does not stump you. Excel rewards people who reference cells instead of typing values and who keep inputs separate from formulas, because that is what makes a result you can audit months later. Build it once, deliberately, with the live tool as a check, and you convert a one-off lookup into a reusable skill — which is the whole point of learning the why and not just the what.

Common mistakes

• Forgetting to format a date sequence, which shows serial numbers.
• Generating a block larger than the empty space available, which returns #SPILL!.
• Using it in Excel 2019 or earlier, where it does not exist.
