1. VLOOKUP
What It Does
VLOOKUP (Vertical Lookup) searches for a value in the first column of a range and returns a value in the same row from a specified column.
Syntax
VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])
Example
=VLOOKUP(A2, B2:D10, 3, FALSE)
Use Case
Finding the price of a product by looking up its ID in a product catalog.
2. INDEX and MATCH
What It Does
INDEX returns the value of a cell in a specified array, and MATCH returns the relative position of an item in an array that matches a specified value.
Syntax
INDEX(array, row_num, [column_num])
MATCH(lookup_value, lookup_array, [match_type])
Example
=INDEX(B2:B10, MATCH(E2, A2:A10, 0))
Use Case
Combining INDEX and MATCH to perform a more flexible lookup than VLOOKUP.
3. SUMIFS
What It Does
SUMIFS adds the cells specified by a given set of conditions or criteria.
Syntax
SUMIFS(sum_range, criteria_range1, criteria1, [criteria_range2, criteria2], ...)
Example
=SUMIFS(C2:C10, A2:A10, "Product A", B2:B10, ">100")
Use Case
Calculating the total sales of "Product A" where the quantity sold is greater than 100.
4. COUNTIFS
What It Does
COUNTIFS counts the number of cells that meet one or more criteria.
Syntax
COUNTIFS(criteria_range1, criteria1, [criteria_range2, criteria2], ...)
Example
=COUNTIFS(A2:A10, "Product A", B2:B10, ">100")
Use Case
Counting the number of occurrences where "Product A" sales exceed 100 units.
5. IF and Nested IF
What It Does
IF performs a logical test and returns one value for a TRUE result and another for a FALSE result. Nested IF statements allow multiple conditions.
Syntax
IF(logical_test, value_if_true, value_if_false)
Example
=IF(A2>100, "High", IF(A2>50, "Medium", "Low"))
Use Case
Classifying sales numbers into categories such as "High," "Medium," and "Low."
6. CONCATENATE (or CONCAT)
What It Does
CONCATENATE joins multiple text strings into one.
Syntax
CONCATENATE(text1, [text2], ...)
Example
=CONCATENATE(A2, " ", B2)
Use Case
Combining first and last names from two columns into one full name column.
7. LEFT, RIGHT, MID
What It Does
LEFT returns the first characters in a text string, RIGHT returns the last characters, and MID returns a specified number of characters from the middle of a text string.
Syntax
LEFT(text, [num_chars])
RIGHT(text, [num_chars])
MID(text, start_num, num_chars)
Example
=LEFT(A2, 5)
=RIGHT(A2, 3)
=MID(A2, 2, 4)
Use Case
Extracting specific parts of a string, such as area codes from phone numbers.
8. PIVOT TABLES
What It Does
Pivot Tables allow you to summarize, analyze, explore, and present summary data.
Syntax
Insert > PivotTable
Example
Creating a Pivot Table to analyze sales data by region and product.
Use Case
Summarizing large datasets to identify patterns and trends.
9. TEXT
What It Does
TEXT converts a value to text in a specific number format.
Syntax
TEXT(value, format_text)
Example
=TEXT(A2, "mm/dd/yyyy")
Use Case
Formatting dates and numbers for better readability.
10. ARRAY FORMULAS
What It Does
Array formulas perform multiple calculations on one or more sets of values and return either a single result or multiple results.
Syntax
{=formula}
Example
{=SUM(A2:A10*B2:B10)}
Use Case
Performing complex calculations such as sum products without using helper columns.
