How to Fix Green Cell or Green Line Error on Google Sheets

Google Sheets users face problems when they see a green line after a few cells, or cells carrying a green border. That can be problematic or just a bad case of conditional formatting. In some cases, this can damage the data set, and you don’t want it. This post will guide you on how to fix green cells or green line errors on Google Sheets.


Why does Google suddenly highlight these cells? Why are green cells on Google Sheets? Why is there a green line after the cell? We will find out all about that. There may be a number of reasons for this strange event, and we will discuss it in this guide.

Let’s get started.

1. Highlighted by Search

Are you looking for something in Google Sheets? Your browser or Sheets document will highlight cells that contain the value you are looking for to make it easier for you to find it. Common Ctrl + F keyboard shortcuts.


It is also possible that the search bar is not visible but is still searching in the background which results in the cell being highlighted. Check browser search and delete immediately.

2. Open File Elsewhere

Do you see a green border around certain cells? The cell is not filled with color here. That is a sign that the same document is open on different devices or the same device but in different browser tabs. Find out where it opens and close the duplicate example.


This can be your smartphone or laptop office. That can happen even if no one else is using the file or even accessing it.

3. Turn off the filter

Filter options will allow you to understand all the data that you input. You can sort them by various parameters. This will also highlight cells in green. Did you adjust the filter accidentally?


Select the highlighted cell, click on the Data menu, and select the Disable filter option.

4. Conditional Formatting

Conditional formatting allows you to format cells or even whole rows and columns based on your input. It follows the formula of cause and effect. A typical example can highlight cells. For example, rotate all cells with the alphabet ‘a’ (cause) green (effect), as shown in the screenshot below. I know it’s basic, but it’s pretty much the way it works.

Step 1: Select Conditional formatting under the Format menu.


Step 2: Check whether there are formatting sets for cells that turn green and delete them if you find them.


You will see a Delete icon next to each conditional formatting rule. Delete the rules and check whether you can see cells or green lines.


5. Color Changing

You can also format headers and footers in Sheets. If so, only the first or last cell must be highlighted in green.

Step 1: Click on Format and select the Alternate color option.


Step 2: Click on the Delete alternating color option at the bottom of the right sidebar that just appeared open. You can also adjust it if you want.


Bonus Tip: Protected Cells

Here is a bonus tip that will ensure that you don’t face this problem in the future where cells turn green or see a green line after random cells on Google Sheets.

Sometimes, you press the wrong keyboard shortcuts and mess up everything. To avoid such situations, simply lock the cell range.

Step 1: Select the range of cells that you want to protect from further changes. Right-click on the selected cell range and select the Protect range option.


Step 2: You can enter a description to remember why you locked the cell range. If you share the sheet with other people, they will know what they shouldn’t do. Click on Permissions now.


Step 3: You can choose to display a warning message when someone tries to edit a cell range. It’s entirely up to you.


You can also set permissions for everyone who can edit protected cell ranges. What else? You can also copy permissions from other cell ranges that you previously protected in the drop-down menu. Just select ‘Copy permissions from another range.’ Click Finish to save changes.
