Excel is a powerful tool for data analysis, and mastering its formulas can significantly enhance your productivity. This blog post will delve into ten essential Excel formulas, providing clear explanations, examples, and practical applications.

## Sample Dataset

To illustrate the formulas, we’ll use the following dataset:

Product | Quantity | Price | Total Sales |
---|---|---|---|

Apple | 10 | 2 | 20 |

Banana | 5 | 3 | 15 |

Orange | 8 | 2.5 | 20 |

Mango | 3 | 1.5 | 4.5 |

Pineapple | 2 | 4 | 8 |

Grapes | 7 | 1.2 | 8.4 |

Watermelon | 1 | 5 | 5 |

Strawberry | 4 | 2 | 8 |

Cantaloupe | 6 | 3 | 18 |

Honeydew | 9 | 1.8 | 16.2 |

## 1. SUM: Calculate the Total

**Purpose:** Adds up all numbers in a specified range.**Syntax:** `=SUM(number1, number2, …)`

**Example:** `=SUM(B2:B11)`

**Result:** `55`

(total quantity of all products)

## 2. AVERAGE: Determine the Mean

**Purpose:** Calculates the average of a set of numbers.**Syntax:** `=AVERAGE(number1, number2, …)`

**Example:** `=AVERAGE(C2:C11)`

**Result:** `2.46`

(average price of all products)

## 3. COUNT: Count Cells

**Purpose:** Counts the number of cells that contain numbers.**Syntax:** `=COUNT(value1, value2, …)`

**Example:** `=COUNT(A2:A11)`

**Result:** `10`

(total number of products)

## 4. COUNTIF: Count Based on Criteria

**Purpose:** Counts the number of cells within a range that meet a specific condition.**Syntax:** `=COUNTIF(range, criteria)`

**Example:** `=COUNTIF(D2:D11,">100")`

**Result:** `0`

(no products with total sales over 100)

## 5. IF: Make Decisions

**Purpose:** Performs a logical test and returns one value if true, another if false.**Syntax:** `=IF(logical_test, value_if_true, value_if_false)`

**Example:** `=IF(B2>1000, "High Quantity", "Low Quantity")`

**Result:** `"Low Quantity"`

for all rows (since no quantity is over 1000)

## 6. VLOOKUP: Find Data in a Table

**Purpose:** Searches for a specific value in the leftmost column of a table and returns a corresponding value.**Syntax:** `=VLOOKUP(lookup_value, table_array, col_index_num, [range_lookup])`

**Example:** `=VLOOKUP(A2, A1:D11, 3, FALSE)`

**Result:** Returns the price of the product in A2 (e.g., `2`

for Apple)

## 7. CONCATENATE: Combine Text

**Purpose:** Joins multiple text strings into one text string.**Syntax:** `=CONCATENATE(text1, text2, …)`

**Example:** `=CONCATENATE(A2, " Fruit")`

**Result:** Creates a new text string (e.g., `"Apple Fruit"`

)

## 8. MAX and MIN: Find Extremes

**Purpose:** Find the largest or smallest value in a range.**Syntax:** `=MAX(number1, number2, …)`

or `=MIN(number1, number2, …)`

**Example:** `=MAX(D2:D11)`

**Result:** `20`

(highest total sales)**Example:** `=MIN(D2:D11)`

**Result:** `4.5`

(lowest total sales)

## 9. TODAY: Insert Current Date

**Purpose:** Returns the current date.**Syntax:** `=TODAY()`

**Result:** Displays the current date (e.g., `July 25, 2024`

)

## 10. SUMIF: Conditional Sum

**Purpose:** Adds up values in a range based on a given criteria.**Syntax:** `=SUMIF(range, criteria, [sum_range])`

**Example:** `=SUMIF(A2:A11, "Apple", B2:B11)`

**Result:** `10`

(total quantity of apples)
