Here’s a list of the Top 10 Excel functions that are most widely used and extremely useful for data analysis, reporting, and daily business tasks:
1. VLOOKUP / XLOOKUP
-
VLOOKUP helps to search for a value in the first column of a range and return a value from another column.
-
XLOOKUP (newer & more powerful) can search in both directions and replace VLOOKUP & HLOOKUP.
👉 Example: =XLOOKUP(105, A2:A10, C2:C10)
2. IF
-
Used to perform logical tests and return different results based on TRUE or FALSE conditions.
👉 Example: =IF(B2>=50,"Pass","Fail")
3. SUM & SUMIF / SUMIFS
-
SUM adds numbers quickly.
-
SUMIF / SUMIFS add numbers based on single or multiple conditions.
👉 Example: =SUMIF(A2:A10,"Apples",B2:B10)
4. INDEX & MATCH
-
A powerful combo that replaces VLOOKUP, allowing more flexibility.
-
INDEX returns a value from a table by row & column number.
-
MATCH gives the position of a value in a range.
👉 Example: =INDEX(C2:C10, MATCH(105, A2:A10, 0))
5. TEXT Functions (LEFT, RIGHT, MID, LEN, TRIM, CONCAT / TEXTJOIN)
-
Help in cleaning and formatting text.
-
LEFT/RIGHT extract characters.
-
CONCAT / TEXTJOIN join text easily.
👉 Example: =TEXTJOIN(" ",TRUE,A2:A5)
6. PROPER, UPPER, LOWER
-
Useful for formatting names and text consistently.
👉 Example: =PROPER("john smith")
→ "John Smith"
7. ROUND, ROUNDUP, ROUNDDOWN
-
Round numbers to required decimal places.
👉 Example: =ROUND(123.456,2)
→ 123.46
8. TODAY & NOW
-
Insert the current date/time dynamically.
👉 Example: =TODAY()
→ 06-Sep-2025
9. COUNT, COUNTA, COUNTIF / COUNTIFS
-
COUNT → counts numbers.
-
COUNTA → counts non-empty cells.
-
COUNTIF / COUNTIFS → counts based on conditions.
👉 Example: =COUNTIF(A2:A10,"Apples")
10. PivotTables (not a single function, but a feature)
-
Summarizes large datasets with drag-and-drop ease.
Allows grouping, filtering, and aggregating data.
