In Excel: select one cell in the table, choose Data ▸ Sort, tick My data has headers, pick the column and order, and expand the selection so whole rows move together.

What this does
Sorting reorders rows by one or more columns. The key safety rule is that whole records must move together; sorting a single column by itself can detach names, dates and amounts from one another. Dates sort correctly only when Excel recognizes them as real dates, not text. Before you run it on a workbook other people depend on, try it on a copy or a few rows first. Undo only reaches back through the current session, so a quick trial run is the cheapest way to see exactly what will change before the file is saved and shared. The difference between a quick fix and a sheet you can trust is the extra minute you spend validating “sort by last name in excel”. 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 this is a ribbon command, the selection matters more than the button: confirm the range, apply the command, then spot-check the output before saving. The point is a data step that keeps your analysis trustworthy, but the practical win is that someone else can open the file and understand what happened without asking you.
A worked example
A table has Customer, Date and Amount. Click inside it, choose Data ▸ Sort, tick My data has headers, sort by Date from Oldest to Newest, then add a level for Amount largest to smallest. Each row stays intact while the table order changes. Sorting is simple but high-risk: done correctly it reveals order and priority; done on the wrong range it corrupts the dataset. When the result is not what you expected, undo straight away rather than repairing it by hand — undo restores the sheet exactly, while manual fixes tend to leave small inconsistencies behind that surface later.
In Google Sheets
This is a command rather than a formula, so there is no syntax to carry over. Google Sheets arranges its commands in menus across the top instead of a ribbon, names some of them differently and does not have every Excel command — look for the equivalent in the Sheets menus or its help before assuming the steps match. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. The short version of “sort by last name in excel”: the answer is at the top of this page, and the sections above explain why each step matters, so a variation of the problem does not stump you. Try it once on a copy of a real file and the steps stick far better than re-reading them.
Common mistakes
- Sorting only one column and corrupting row relationships.
- Sorting dates stored as text, which can order alphabetically instead of chronologically.
- Leaving blank rows that split the detected table range.
- Forgetting to include hidden rows if they should be sorted too.
