Use the free VLOOKUP Formula Generator below: your data never leaves your browser — all work happens on your device, and nothing is uploaded to any server.
Spreadsheets store facts in tables, and looking up a fact by a key is one of the most common spreadsheet jobs. Find the price for this product code, the name for this employee number, or the grade for this student ID. Typing those lookup formulas by hand is slow and error-prone: one wrong column number, one missing comma, and the formula returns the wrong answer or an error. The VLOOKUP Formula Generator assembles the formula from your inputs and gives you a string ready to paste into a cell.
This tool is built for spreadsheet users, not for formula experts. You do not need an account, an install, or an upload. Everything happens in your browser, on your own device. Your inputs never leave the page, and nothing is sent to a server. The output is a formula string, not a connection to your spreadsheet, so your data stays exactly where it is.
To use it, pick a formula style: VLOOKUP or XLOOKUP. Enter the lookup value, such as a cell reference like A2 that holds the key you are searching for. Enter the table range, such as Sheet2!A:B, which is the table to search. For VLOOKUP, enter the return column number, counting from the first column of the range: 2 means the second column. For XLOOKUP, enter the return range instead, such as Sheet2!B:B. Choose exact or approximate match, and optionally a value to show when nothing is found. Press Build formula and the result appears, ready to copy.
VLOOKUP and XLOOKUP differ in ways that decide which one to use. VLOOKUP only looks to the right: the key must sit in the first column of the range, and the answer must come from a column to its right. It needs a column number, which breaks if someone inserts a column inside the range, because the numbers shift. XLOOKUP has no such limits: it can look in any direction, it uses a return range instead of a fragile column number, and it has a built-in if-not-found value. The catch is compatibility: older Excel versions support VLOOKUP but not XLOOKUP, so a file shared with someone on old software should use VLOOKUP, while a file for modern Excel or Google Sheets users can use XLOOKUP.
Exact match is the right choice for almost every lookup of codes, names, and IDs. With exact match, the formula finds the row whose key equals your lookup value, or reports not found. Approximate match is a specialist tool for sorted ranges, such as tax bands or grade boundaries, where the answer is the largest value not greater than the lookup value. Using approximate match on an unsorted list of codes gives a confident-looking wrong answer, which is worse than an error, so leave exact match on unless you know your range is sorted and you need a band lookup.
The if-not-found value deserves a thought too. Without it, a missed lookup shows an error that can cascade through other formulas. With it, the cell shows a readable message such as Not found, which is friendlier in a report but can hide a real problem if a key was mistyped. For a working sheet, an error that shouts is sometimes better than a polite message that hides a typo, so choose based on who will read the sheet and whether misses should be investigated.
Common mistakes are easy to avoid once you know them. Extra spaces in a key stop an exact match, because the text no longer equals the stored key. Numbers stored as text do not match real numbers, which is a frequent cause of mysterious failures after an import. Duplicate keys return the first match only, so a lookup cannot warn you that two rows share a key. Check the key column for duplicates and stray spaces before blaming the formula.
Small businesses use lookups to price orders from a product table, teachers use them to pull grades from a register, and anyone with two sheets and a shared key uses them daily. A generated formula removes the syntax errors, leaving only the data checks, which is where your attention belongs.
How to build a lookup formula
- Pick VLOOKUP for older Excel, XLOOKUP for modern Excel or Sheets.
- Enter the lookup value cell, the table range, and the return column or range.
- Leave exact match on unless you need a sorted band lookup.
- Press Build formula and copy the result into a cell.
Frequently asked questions
VLOOKUP or XLOOKUP? XLOOKUP is more flexible and robust, but older Excel versions lack it. Use VLOOKUP for files shared with old Excel.
Why does my lookup return an error? Usually a stray space, a number stored as text, or a key that is genuinely absent. Check the key first.
Does it read my spreadsheet? No. It builds a formula string from your inputs. Paste it into your own sheet.
Is my data uploaded? No. All generation happens in your browser.
Fill in the pieces, copy the formula, and paste it into your sheet. The syntax is handled; your job is to check that the key matches, which is the part that actually decides whether the answer is right.
