In Excel: type = and click the cell — within a sheet that gives =B4, on another sheet ='Sheet2'!B4, and in another workbook =[Budget.xlsx]Sheet1!B4.
On this page7
Type = in the target cell and click the cell you want; Excel writes the reference for you.
To reach another sheet, type = then click that sheet's tab and then the cell.
Press F4 while the reference is selected in the formula bar to cycle B4 → $B$4 → B$4 → $B4.
Lock anything you will fill across or down that must not move, such as a rate or a lookup range.
For the same cell across many sheets, use the 3-D form =SUM(FirstSheet:LastSheet!B4).
For a reference that survives inserted rows and columns, name the cell (Formulas ▸ Define Name) and use the name.
What this does
A reference points at a cell instead of copying its value, so the formula follows the data. Three things vary. Scope: a bare B4 means this sheet, Sheet2!B4 means another sheet in this workbook (quoted as 'Sheet 2'!B4 when the name contains a space), and [Book.xlsx]Sheet1!B4 means another file. Anchoring: B4 shifts when the formula is copied, $B$4 never does, and the mixed forms B$4 and $B4 lock one axis — F4 cycles through the four. And style: A1 is the default, while R1C1 (File ▸ Options ▸ Formulas) numbers the columns instead, which is what you see if a colleague turns it on. A 3-D reference like =SUM(Jan:Dec!B4) spans the same cell across a run of sheets. Keep the inputs visible and clearly labelled and the whole thing stays auditable — anyone who opens the file later, including you, can see at a glance exactly what feeds the result and change one assumption without hunting through the formula. Treat “reference other sheets 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 sheet 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 layout choice that keeps the sheet readable and sortable into a method you can reuse, explain, and defend when the workbook leaves your screen.
A worked example
In a summary sheet, =Sheet2!B4 pulls one figure from another tab; the quotes appear automatically if the sheet is named 'Q1 Data'. Copying =B4*C4 from row 4 to row 5 makes it =B5*C5. To hold the tax rate in $B$1 while filling down, write =B4*$B$1 — the B4 moves, the $B$1 does not. Across twelve monthly sheets with the same layout, =SUM(Jan:Dec!B4) totals cell B4 on all of them. Every formula is built out of references, and the relative-versus-absolute distinction is the single most common reason a formula that worked in one row returns nonsense in the next. If there is any chance you will reuse this, drop it into a small template tab right now: a labelled input area on the left and the formula beside it, checked once against the tool above. Next time the same question comes up, the answer is a single paste away instead of a rebuild from memory.
In Google Sheets
References to another workbook do not carry over: Excel's [Workbook.xlsx]Sheet1!B4 syntax is not valid in Google Sheets, where data from another spreadsheet is pulled in with IMPORTRANGE. References to another tab in the same file (Sheet2!B4) work in both. Excel's 3-D references that span several sheets, such as =SUM(Jan:Dec!B4), are not supported in Google Sheets; there you add the sheets individually, for example =SUM(Jan!B4, Feb!B4, Mar!B4). Nothing on this page is behind a login or a download: the exact answer is at the top, and the detail below it is there for when you need it. That is the whole promise here — the answer first, and just enough context to make it stick. If you take one thing from this page on “reference other sheets in excel”, make it the habit rather than the keystrokes: set the problem up with labelled inputs, reference those cells, and let Excel do the recomputing. Bookmark the page for the syntax, but do the example once in a blank sheet and check it against the tool above — five minutes of hands-on practice fixes the method in memory far better than re-reading, and it surfaces the small snags while they are still harmless. After that the technique is genuinely yours: faster than searching for it again, and reliable enough to drop into work that other people depend on.
Common mistakes
- Filling a formula down with a relative reference to a rate cell, so row 2 reads
B1and row 3 readsB2. - Typing sheet names by hand and missing the quotes a space requires: ='
Q1Data'!B4. - Linking to another workbook and then moving it, which turns the reference into a broken path.
- Using $ everywhere out of caution, which stops formulas adapting when they should.
- Panicking at R1C1 style when a colleague enabled it — it is a display option in File ▸ Options ▸ Formulas.
Frequently asked questions
How do I reference a cell in Excel?
Type = and click the cell. Within a sheet that gives =B4; on another sheet it becomes =Sheet2!B4, with quotes around the name if it contains a space.
What is the difference between B4 and $B$4?
B4 is relative and shifts when the formula is copied. $B$4 is absolute and always points at the same cell. B$4 and $B4 lock only the row or only the column. F4 cycles through all four.
How do I reference a cell in another workbook?
=[Budget.xlsx]Sheet1!B4 while both files are open; Excel writes the full path once the source is closed. Moving or renaming the source breaks the link.
How do I sum the same cell across many sheets?
Use a 3-D reference: =SUM(Jan:Dec!B4) totals B4 on every sheet from Jan to Dec inclusive.
