How to remove duplicates in Excel with WPS Office
Use WPS Spreadsheet (Excel-compatible) on the Data tab: Highlight Duplicates, Remove Duplicates, or UNIQUE. Pick inspect-first, delete-in-place, or a new clean table.
Back up your file before changing data—duplicate removal cannot be undone after you save.
Method 1: Highlight Duplicates on the Data tab
Inspect repeats before you delete anything.
Open the sheet and select key cells
Open WPS Spreadsheet and select columns with unique IDs (e.g. email or order ID).
Data → Highlight Duplicates → Set
Open the Data tab → Highlight Duplicates → Set.
Confirm the range
Check the range in the dialog, adjust if needed, then click OK.
Review orange highlights
Duplicates appear in orange.
Expert tip: Highlight on one ID column first—fewer false positives than selecting the whole table.
Method 2: Remove Duplicates (delete rows)
Delete repeated rows from the selected range.
Select the data to clean
Open your sheet and select the range where duplicate rows should be removed.
Data → Remove Duplicates
Go to Data, expand Highlight Duplicates, then click Remove Duplicates.
Choose columns to evaluate
In the Remove Duplicates window, select columns and review the duplicate count.
Run cleanup and confirm
Click Remove Duplicates, read the count dialog, then click OK.
Expert tip: Tick only columns that define a true duplicate (e.g. Order ID), not notes or amounts.
Method 3: UNIQUE formula (non-destructive)
Build a deduped copy; original data stays intact.
Start =UNIQUE( in an empty cell
Pick an empty cell, type =UNIQUE(, select the function from suggestions, then press Tab.
Select the full table as the array
UNIQUE has one argument: select the entire table as the array and press Enter.
Use the new clean table
WPS Spreadsheet returns a deduped table for reporting and analysis.
Expert tip: UNIQUE is ideal for audits—you keep the source sheet unchanged for data management trails.
- Highlight Duplicates — preview only.
- Remove Duplicates — permanent row delete.
- UNIQUE — new table; source preserved.
