Excel Lookup Another Sheet

What this does

VLOOKUP finds a value in the first column of a table and returns a value from a column to its right on the same row — the classic way to pull a price from a product code or a name from an ID. The fourth argument is the one that bites: FALSE (or 0) demands an exact match, which is almost always what you want; TRUE assumes the first column is sorted and does an approximate match. 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. For “excel lookup another sheet”, the reliable version is a short checking loop, not just the first command that appears to work. Run it on a deliberately small range first, watch how the affected sheet change, and only then apply the same setup to the full sheet. 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 is what makes a layout choice that keeps the sheet readable and sortable useful in real work: repeatable, auditable, and not dependent on memory or luck.

A worked example

With product codes in column A and prices in column B, =VLOOKUP("SKU-204", A2:B100, 2, FALSE) returns the price next to SKU-204. The 2 means “second column of the range”. If the code is not found you get #N/A — wrap it as =IFERROR(VLOOKUP(...), "not found") to show a friendly message instead. Lookups are how separate tables talk to each other — joining orders to customers, codes to descriptions, IDs to prices. Mastering VLOOKUP (and its successor XLOOKUP) turns a pile of sheets into a connected model. A practical tip before you scale it up: build it once on a small block of test data, confirm the number against the tool on this page, and only then point it at your real sheet. That one habit catches almost every mistake while it is still cheap to fix, long before a wrong figure reaches a report or a colleague.

In Google Sheets

If you are in Google Sheets rather than Excel, the good news is that the formula shown here is identical and the workflow barely changes — menus sit across the top instead of in a ribbon, and a few function names differ slightly, but anything you build here moves across with little or no rework. Keep this page bookmarked for the next time the same question comes up. Better still, repeat the steps once in your own workbook — doing it yourself is what turns a copied answer into something you remember. Treat “excel lookup another sheet” as a small building block rather than a chore. Once the inputs sit in their own cells and the formula reads from them, the same setup answers a dozen related questions with a tweak, and Excel keeps every dependent figure current as the data changes. The tool above is there so you can rehearse and verify before committing anything to a real workbook; the steps and worked example are there so the logic sticks. Get it right once and it stops costing you time — it starts saving it, every time the question comes back around.

Common mistakes

• Omitting FALSE, so VLOOKUP returns a wrong approximate match on unsorted data.
• Counting the column number from the sheet rather than from the start of the table range.
• Looking up a value that is not in the leftmost column — VLOOKUP only looks right.
• Breaking the formula by inserting a column inside the table; use XLOOKUP or INDEX/MATCH for resilience.
