# Google Sheets Formulas: A Comprehensive Guide

Google Sheets is a powerful tool for data analysis and manipulation.

One of its most useful features is the ability to use formulas to perform calculations on your data.

In this article, we will provide a comprehensive guide to some of the best formulas in Google Sheets, along with examples and templates to help you get started.

## SUM Formula

The SUM formula is one of the most basic and commonly used formulas in Google Sheets.

It allows you to add up the values in a range of cells.

For example, if you have a column of numbers in cells A1 through A10, you can use the SUM formula to add them all up.

The syntax for the SUM formula is `=SUM(range)`, where range is the range of cells that you want to add up.

## COUNT Formula

The COUNT formula is another basic formula that is used to count the number of cells in a range that contain numbers.

This can be useful for quickly getting a sense of how much data you have in a particular column or row.

The syntax for the COUNT formula is `=COUNT(range)`, where range is the range of cells that you want to count.

## AVERAGE Formula

The AVERAGE formula is used to calculate the average of a range of cells.

This can be useful for understanding the overall trend of a set of data.

The syntax for the AVERAGE formula is `=AVERAGE(range)`, where range is the range of cells that you want to average.

## VLOOKUP Formula

The VLOOKUP formula is a powerful formula that allows you to search for a specific value in a table and return a corresponding value from another column.

This can be useful for pulling data from one sheet into another, or for combining data from multiple sources.

The syntax for the VLOOKUP formula is `=VLOOKUP(search_value, range, column_number, [approximate_match])`, where search_value is the value that you are looking for, range is the range of cells that you want to search, column_number is the column number of the value that you want to return, and approximate_match is an optional argument that controls whether or not the formula should return an approximate match.

## INDEX-MATCH Formula

The INDEX-MATCH formula is a powerful formula that is similar to the VLOOKUP formula.

However, it is more flexible and allows you to search for a value in one column and return a corresponding value from another column.

The syntax for the INDEX-MATCH formula is `=INDEX(range, MATCH(search_value, range, match_type))`, where range is the range of cells that you want to search, search_value is the value that you are looking for, and match_type is an optional argument that controls how the formula should match the search value.

## DATEDIF Formula

The DATEDIF formula is a useful formula for calculating the number of days, months, or years between two dates.

This can be useful for tracking deadlines or measuring the duration of a project.

The syntax for the DATEDIF formula is `=DATEDIF(start_date, end_date, unit)`, where start_date is the start date, end_date is the end date, and unit is the unit of time that you want to use (days, months, or years).

## IF Formula

The IF formula is a powerful formula that allows you to perform conditional calculations in Google Sheets.

This can be useful for creating dynamic formulas that change based on certain conditions.

The syntax for the IF formula is `=IF(condition, value_if_true, value_if_false)`, where condition is the logical test that you want to perform, value_if_true is the value that should be returned if the condition is true, and value_if_false is the value that should be returned if the condition is false.

For example, you could use the IF formula to check if a certain cell is above a certain value and return “high” if it is, and “low” if it is not.

The formula would be `=IF(A1>50, "high", "low")`.

## IFERROR Formula

The IFERROR formula is used to check if a formula returns an error, and if it does, return a specified value instead.

This can be useful for preventing errors from disrupting your data analysis.

The syntax for the IFERROR formula is `=IFERROR(formula, value_if_error)`, where formula is the formula that you want to check for errors, and value_if_error is the value that should be returned if an error is found.

The formula would be `=IFERROR(VLOOKUP(A1, A2:B10, 2, FALSE), "Not found")`.
