## #1: SUM function

The SUM function is the most widely used Excel function in the world. It is present in all Excel workbooks without exception. Don't underestimate this function! Many people still write A1+A2+A3+A4+ .... when they want to add cells together.

This function is so useful that you can create a sum directly from the ribbon (like in this example) or with the shortcut Alt+=

## #2: IF function

In many situations, you must compare 2 data against each other. Depending on the test result, you will have to return a different answer. It is in this kind of situation that the IF function will prove to be very useful.

## #3: COUNTIF and COUNTIFS

The COUNTIF function in Excel offers the benefits of quickly and accurately counting the occurrences of a specific criterion within a range of cells.

It simplifies data analysis, enables efficient tracking of data patterns, and provides valuable insights for decision-making, all in a concise and user-friendly manner.

• COUNTIF can use only one column for the criterion
• COUNTIFS can calculate the number of rows for 256 columns of criteria maximum.

## #4: SUMIF and SUMIFS

The SUMIF and SUMIFS functions in Excel count and sum values based on specified criteria or many criteria for SUMIFS. This allows for more advanced calculations and analysis compared to the simpler counting functionality of the COUNTIF function.

## #5: UNIQUE function

As the name suggests, the UNIQUE function will return a list of data without duplicates. Its use is straightforward because it is enough to fill the column to be treated.

## #6: FILTER

The FILTER function was released in 2018 and has become one of the most useful Excel functions.

The FILTER function in Excel provides several benefits: efficient data filtering, flexibility to extract specific information, simplified data analysis, improved visibility of relevant data, and enhanced productivity by automating filtering tasks.

## #7: XLOOKUP

The XLOOKUP function in Excel offers advantages over VLOOKUP, such as searching in any column, handling unsorted data, returning multiple matches, and supporting vertical or horizontal lookups.

It simplifies and enhances data retrieval tasks with increased flexibility and efficiency.

## #8: TRIM

Because most raw data are not clean, the TRIM function in Excel removes leading, trailing, and extra spaces within a cell, resulting in cleaner and more consistent data. Of course, you must also perform a paste special in value to keep only the result and not the formula.

## #9: TEXTJOIN

The TEXTJOIN function in Excel allows for quick and easy concatenation of multiple text values. It simplifies complex formulas, improves data organization, and enhances readability by eliminating the need for manual text manipulation.

## #10: DATE

The DATE function in Excel creates a valid date based on individual year, month, and day values. It helps perform calculations, comparisons, and date-related operations in spreadsheets, facilitating data analysis and organization.
