How to Use FILTER, UNIQUE, and SEQUENCE in Excel
Excel’s modern dynamic array functions — FILTER, UNIQUE, and SEQUENCE — simplify data handling by automatically spilling results into multiple cells. Let’s explore how to use them effectively.
Pro Tip: These formulas are available in Excel 365 and Google Sheets. They save time and reduce errors in data analysis.
1) FILTER — Extract Specific Data
The FILTER function extracts data that meets specific conditions.
=FILTER(A2:C20, C2:C20="North")This will return only the rows where the region is “North”.
2) UNIQUE — Remove Duplicates
The UNIQUE function generates a list of distinct values.
=UNIQUE(B2:B100)This formula lists all unique entries from column B.
3) SEQUENCE — Generate Numbers Automatically
The SEQUENCE function creates a range of sequential numbers.
=SEQUENCE(10,1,1,1)This produces numbers 1 to 10 in a column.
4) Combining FILTER, UNIQUE, and SEQUENCE
You can combine these formulas for advanced automation:
=SORT(UNIQUE(FILTER(A2:A100, B2:B100="Completed")))This returns a sorted list of unique items from column A where column B = “Completed”.
Why Use These Functions?
- Efficiency: Work with large datasets instantly.
- Automation: Results update dynamically with source data.
- Simplicity: Reduce formula complexity while improving accuracy.
Recommendation: Start using these functions in Excel 365 or Google Sheets to boost productivity.
