π¨ One duplicate invoice can create a big problem. Can you spot it before itβs too late?
Imagine youβre preparing a monthly sales or finance report with hundreds of invoice numbers. Everything looks perfectβ¦ until you accidentally process the same invoice twice.
Instead of checking every row manually, let Excel do the work for you.
β
Select the column containing your invoice numbers (or customer IDs, employee IDs, product codes, etc.).
β
Go to Home β Conditional Formatting β Highlight Cells Rules β Duplicate Values.
β
Click OK.
Thatβs it! Excel instantly highlights every duplicate, helping you catch mistakes before they affect your report.
π‘ Example:
If invoice INV-1025 appears twice, Excel will highlight both entries immediately. You can then review them and decide whether theyβre genuine duplicates or valid repeated records.
β οΈ Important: This feature only highlights duplicatesβit does not delete them. That makes it a safe first step before cleaning your data.
This simple trick is especially useful for:
βοΈ Finance reports
βοΈ Customer databases
βοΈ Employee records
βοΈ Inventory lists
βοΈ Sales reports
