Replacing Tabs with Spaces in Gedit

Ubuntu 11

Gedit is a powerful text editor, often used by developers and system administrators. One common task that users often need to perform is replacing tabs with spaces. This task can be accomplished with ease in Gedit and this article will guide you through the process in a detailed and comprehensive manner.

Quick Answer

To replace tabs with spaces in Gedit, you can use the built-in Replace feature. Simply open your file in Gedit, press Ctrl+H to open the Replace dialog box, enter "\t" in the Search field, and enter the desired number of spaces in the Replace with field. Click on Replace All to replace all tabs with spaces. Additionally, you can configure Gedit to insert spaces instead of tabs by going to Edit > Preferences, navigating to the Editor tab, and selecting the Insert spaces instead of tabs checkbox.

Why Replace Tabs with Spaces?

Before we dive into the how, let’s briefly discuss the why. The debate between using tabs or spaces for indentation is a long-standing one in the programming community. However, some languages like Python are particularly sensitive to whitespace and require consistent use of either tabs or spaces for indentation. Additionally, spaces are generally more universally consistent across different text editors and environments.

Replacing Tabs with Spaces Using the Replace Feature

Gedit comes with a built-in feature that allows you to replace characters, including tabs, with other characters. Here’s how to use this feature:

  1. Open your file in Gedit. Navigate to the location of your file and open it with Gedit.
  2. Open the Replace dialog box. Press Ctrl+H to open the Replace dialog box. This dialog box allows you to search for specific characters in your file and replace them with other characters.
  3. Enter the tab character in the Search field. In the Search field of the Replace dialog box, enter \t. This represents a tab character.
  4. Enter spaces in the Replace with field. In the Replace with field, enter four spaces (or however many spaces you want to replace each tab with).
  5. Replace all tabs with spaces. Click on the Replace All button to replace all tabs in your file with spaces.

Configuring Gedit to Insert Spaces Instead of Tabs

Gedit allows you to configure its behavior so that it inserts spaces when you press the tab key. Here’s how to do it:

  1. Open Gedit Preferences. Go to Edit > Preferences in the Gedit menu to open the Preferences dialog box.
  2. Navigate to the Editor tab. In the Preferences dialog box, click on the Editor tab to view editor-specific settings.
  3. Change the tab settings. Under the Indentation section, select the Insert spaces instead of tabs checkbox. This will ensure that Gedit inserts spaces whenever you press the tab key.

Checking Project Properties

If you’re working on a project, you might also need to check the project properties. Some projects have specific indentation settings that can override the general Gedit settings. To check the project properties, right-click on the project folder and select Properties. Then, navigate to the Indentation tab and ensure that the Insert spaces instead of tabs option is selected.


Replacing tabs with spaces in Gedit is a straightforward process. Whether you’re doing it manually using the Replace feature or configuring Gedit to insert spaces instead of tabs, Gedit provides the tools you need to ensure consistent indentation in your files. Remember to check your project properties if you’re working on a project, as these can sometimes override your general Gedit settings.
