# Sum it Up. How to Get Sum of Column in Google Sheets

## Instructions to Get the Sum of a Column in Google Sheets #

Google Sheets is a powerful tool for organizing and analyzing data. One common task is to calculate the sum of a column. In this article, we will explore two methods to achieve this: manually and using Google Apps Script.

### Manually Calculating the Sum #

To manually calculate the sum of a column in Google Sheets, follow these steps:

1. Open your Google Sheets document containing the column you want to calculate the sum for.
2. Select an empty cell where you want the sum to appear.
3. Type the formula "=SUM(" (without the quotes).
4. Click and drag your cursor to select the range of cells you want to sum. For example, if you want to sum column A from row 2 to row 10, select cells A2:A10.
5. Close the formula by typing a closing bracket ")" and press Enter.

Google Sheets will calculate the sum of the selected range and display the result in the cell you selected. If you update any of the values in the selected range, the sum will automatically be recalculated.

### Using Google Apps Script #

Google Apps Script allows you to automate tasks and extend the functionality of Google Sheets. If you want to calculate the sum of a column dynamically or perform more complex calculations, you can create a custom script.

Follow these steps to create a Google Apps Script to sum a column:

1. Open your Google Sheets document containing the column you want to calculate the sum for.
2. Click on "Extensions" in the top menu, then select "Apps Script" from the dropdown.
3. In the Apps Script editor, delete any existing code and start with the following:
``function sumColumn() {  var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();  var range = sheet.getRange("A2:A"); // Replace "A2:A" with the range of your column    var sum = 0;  var values = range.getValues();    for (var i = 0; i < values.length; i++) {    sum += values[i][0] || 0;  }    return sum;}``
1. Customize the range variable to match the range of your column. For example, if you want to sum column A from row 2 to row 10, change `"A2:A"` to `"A2:A10"`.
2. Save the script by clicking "File" and then "Save" or using the Ctrl + S (Windows) or Command + S (Mac) shortcut.
3. Close the Apps Script editor.

To use the script and calculate the sum:

1. In your Google Sheets document, select an empty cell where you want the sum to appear.
2. In the top menu, click on "Add-ons" and then select "Sum Column" (or the name you gave to your script).
3. The script will calculate the sum of your column and display the result in the selected cell.

### Use Cases for Summing a Column #

Summing a column in Google Sheets can be useful in various scenarios. Here are a few examples:

• Financial tracking: If you have a column that represents monthly expenses, summing the column can provide a quick overview of the total spent.
• Inventory management: If you have a column representing quantities of different products, summing the column can give you the total inventory count.
• Sales analysis: If you have a column with sales figures, summing the column can provide insights into total sales revenue.

By leveraging the manual sum calculation method or creating a custom Google Apps Script, you have the flexibility to automate the calculation of sums in columns and streamline your data analysis in Google Sheets.
