Remove Last Digit in Excel

What this does

Both formulas work the same way: measure the text with LEN, then keep everything except the n characters you are dropping. RIGHT keeps the tail, so it removes from the front; LEFT keeps the head, so it removes from the back. MID(A2, n+1, LEN(A2)) is an equivalent way to say the first, and REPLACE(A2, 1, n, "") an equivalent way again. Microsoft 365 adds two functions that express the intent directly when there is a delimiter to work from: TEXTAFTER(A2, "-") takes everything after the first hyphen and TEXTBEFORE(A2, "-") everything before it, which is more robust than a character count when the prefix length varies. Two cautions apply generally. The result is always TEXT, so a product code stripped of its letter prefix will not behave as a number until you wrap it in VALUE. And if the prefix length is not actually constant, a fixed count silently mangles the rows where it differs — check with =LEN(A2) down the column before trusting it. The same idea underpins a lot of everyday Excel work, so the few minutes spent getting it right here pay back across every sheet you build afterwards. Treat it as a pattern, not a one-off, and it stops being something you look up and starts being something you reach for. Treat “remove last digit 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 cells 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 data step that keeps your analysis trustworthy into a method you can reuse, explain, and defend when the workbook leaves your screen.

A worked example

Codes like P-04821 in A2. =RIGHT(A2, LEN(A2)-2) drops the "P-" leaving 04821 as text; =VALUE(RIGHT(A2, LEN(A2)-2)) gives the number 4821, which also drops the leading zero — so keep it as text if the zero is meaningful. Where the prefix varies (P-, PR-, PROD-), =TEXTAFTER(A2, "-") is correct for all three, and a fixed count is correct for none. Stripped prefixes are what stand between an exported code column and a lookup that matches, and the only real risk is assuming a prefix length that varies. 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

Some functions on this page are newer additions to Excel: they are in current Microsoft 365 and Excel for the web, while older perpetual Excel versions return #NAME?. Google Sheets maintains its own function list, so confirm each function exists there before relying on the same formula. Nothing on this page is behind a login: the tool runs entirely in your browser, the formula is shown in full with one-click copy, and the steps work the same on Windows and Mac. That is the whole promise here — the exact answer, a way to prove it on your own numbers, and just enough context to make it stick. The short version of “remove last digit 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

• Swapping LEFT and RIGHT — RIGHT removes from the start, which reads backwards until you think about which end it keeps.
• Assuming a fixed prefix length and corrupting the rows where it differs.
• Leaving the result as text and then failing to sum or look it up.
• Deleting the source column before pasting the results as values, which fills the column with #REF!.
• Using a character count where trailing spaces are the real problem — TRIM is the right tool for that.
