Functions are key components of spreadsheet applications like Google Sheets. But if you seldom use them, or you’re just beginning, they can feel overwhelming. For the most basic actions you’d perform, here are several simple Google Sheets functions.

It doesn’t get more basic when working with numbers than adding them. Using the `SUM` function, you can add multiple numbers, add numbers in cells, or use a combination.

The syntax for the function is `SUM(value1, value2,...)` with `value1` required and `value2` optional.

To add the numbers 10, 20, and 30, you would use the following formula:

`=SUM(10,20,30)`

To add the numbers in the cells A1 through A5, you would use this formula:

`=SUM(A1:A5)`

## 2. Average Numbers: AVERAGE

Maybe you need to view the average of numbers or numbers in a range of cells. The `AVERAGE` function has you covered.

Similar to calculating average in Excel, the syntax for the Google Sheets function is `AVERAGE(value1, value2,...)` with `value1` required and `value2` optional.

To find the average of numbers 10, 20, and 30, you would use the following formula:

`=AVERAGE(10,20,30)`

To find the average of the numbers in cells A1 through A5, use this formula:

`=AVERAGE(A1:A5)`

Tip: You can also see basic calculations without formulas in Google Sheets.

## 3. Count Cells With Numbers: COUNT

If you’ve ever had to count cells, you’ll appreciate the `COUNT` function. With it, you can count how many cells in a range contain numbers.

The syntax for the function is `COUNT(value1, value2,...)` with `value1` required and `value2` optional.

To count the cells A1 through A5, you would use the following formula:

`=COUNT(A1:A5)`

To count the cells A1 through A5 and D1 through D5, use the following formula:

`=COUNT(A1:A5,D1:D5)`

You can also count data that matches criteria using `COUNTIF` in Google Sheets.

## 4. Enter the Current Date and Time: NOW and TODAY

If you want to see the current date and time each time you open your Google Sheet, you can use the `NOW` or `TODAY` function. `NOW` displays the date and time whereas `TODAY` displays only the current date.

The syntax for each is `NOW()` and `TODAY()` with no required arguments. Simply enter one or the other of the following in your sheet to display the date and time or just the date.

`NOW()`
`TODAY()`

If you want the dates to appear in a certain format, you can set the default date format in Google sheets.

## 5. Remove Non-Printable Characters: CLEAN

When you import data from another location into your sheet, that data can include non-printable or ASCII characters like backspaces and returns. The `CLEAN` function removes both visible and invisible characters.

The syntax is `CLEAN(text)` with the text required.

To remove the non-printable characters from the text in cell A1, you would use this formula:

`=CLEAN(A1)`

Note: Because the function removes the characters you can’t see as well as those you can, you may not notice a difference in the resulting cell.

## 6. Remove White Space: TRIM

Another helpful function for tidying up your sheet is the `TRIM` function. Just like in Microsoft Excel, this function removes the white spaces in a cell.

The syntax is `TRIM(text)` where text can represent a cell reference or the actual text.

To remove the white space in cell A1, you would use the following formula:

`=TRIM(A1)`

To remove the white space from ”   remove   extra space  ” use this formula:

`=TRIM("   remove   extra space  ")`

## 7. Combine Text or Values: CONCATENATE and CONCAT

To combine strings, text, or values, you can use the `CONCATENATE` and `CONCAT` functions. The main difference between the two is that `CONCATENATE` offers more flexibility. For instance, you can combine words and insert spaces between them.

The syntax for each is `CONCATENATE(string1, string2,...)` and `CONCAT(value1, value2)` where all arguments except `string2` are required.

To combine the values in cells A1 and B1, you can use the following formula:

`=CONCATENATE(A1,B1)`

To combine the words “How,” “To,” and “Geek” with spaces, you would use this formula:

`=CONCATENATE("How", " ", "To", " ", "Geek")`

To combine the values 3 and 5, you can use the following formula:

`=CONCAT(3,5)`

## 8. Insert an Image in a Cell: IMAGE

While Google Sheets provides a feature for inserting an image into a cell, the `IMAGE` function gives you extra options to resize it or set a custom height and width in pixels.

The syntax for the function is `IMAGE(url, mode, height, width)` with the URL required and the other arguments optional.

To insert an image with a URL as it is, you would use the following formula:

`=IMAGE("https://logos-download.com/wp-content/uploads/2019/11/How-To_Geek_Logo.png")`

To insert the same image resized with a custom height and width, use this formula:

`=IMAGE("https://logos-download.com/wp-content/uploads/2019/11/How-To_Geek_Logo.png",4,50,200)`

The `4` in this formula is the mode that allows the custom size of the image at 50 by 200 pixels.

Note: You cannot use SVG graphics or URLs for images in Google Drive.

Whether importing or entering data in Google Sheets, you may want to verify it is what it’s supposed to be. With `ISEMAIL` and `ISURL`, you can make sure the data is an email address or valid URL.

The syntax for each is `ISEMAIL(value)` and `ISURL(value)` where you can use a cell reference or text. The results of the validation display as TRUE or FALSE.

To check an email address in cell A1, you would use the following formula:

`=ISEMAIL(A1)`

To check a URL in cell A1, use this formula:

`=ISURL(A1)`

To use text in the formula for either an email address or URL, simply enter it in quotes like this:

`=ISURL("www.howtogeek.com")`

To go even further, take a look at how to use the AND and OR functions, take advantage of the QUERY function, or start using the IF function in Google Sheets.
