Remove First Character

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. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “remove first character”. Start on a copy or a tiny sample, keep the affected cells visible, and compare the result with the tool above before you touch the real workbook. 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. The point is a text operation that turns messy entries into clean, usable data, but the practical win is that someone else can open the file and understand what happened without asking you.

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

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. 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. Here is the takeaway for “remove first character”: copy the answer if you are busy, but if you have a spare few minutes, rebuild the example in Excel yourself with the tool above open beside it. That single pass — type it, run it, watch the result move when you change an input — is what turns a formula you found into a technique you trust. Keep your inputs labelled and referenced, never hard-coded, and the same sheet stays correct and auditable as it grows. Done that way, you will not need to look this up again, and you will be the person others ask.

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.
