Convert Tabs to Spaces in Notepad++

Obsolete: This answer is correct only for an older version of Notepad++. Converting between tabs/spaces is now built into Notepad++ and the TextFX plugin is no longer available in the Plugin Manager dialog.

• First set the "replace by spaces" setting in Preferences -> Language Menu/Tab Settings.
• Next, open the document you wish to replace tabs with.
• Highlight all the text (CTRL+A).
• Then select TextFX -> TextFX Edit -> Leading spaces to tabs or tabs to spaces.

Note: Make sure TextFX Characters plugin is installed (Plugins -> Plugin manager -> Show plugin manager, Installed tab). Otherwise, there will be no TextFX menu.

Settings -> Preference -> Edit Components (tab) -> Tab Setting (group) -> Replace by space

In version 5.6.8 (and above):

Settings -> Preferences... -> Language Menu/Tab Settings -> Tab Settings (group) -> Replace by space

You need to replace \t - make sure you use extended mode!

Follow this procedure to convert spaces to tabs or vice-versa:

The easy way:

1. Highlight a single tab area
2. Copy
3. Bring up find/replace
4. Paste into the find field
5. Click into the replace field and hit the space bar
6. Then replace all.

I did not read all of the answers, but I did not find the answer I was looking for.

I use Python and don't want to do find/replace or 'blank operations' each time I want to compile code...

So the best solution for me is that it happens on the fly!

Here is the simple solution I found:

Go to:

1. Menu Settings -> Preferences
2. Choose Tab Settings
3. Choose your language type (e.g. Python)
4. Select checkbox 'Use default value'
5. Select checkbox 'Replace by space'

In version 5.8.7:

Menu Settings -> Preferences... -> Language Menu/Tab Settings -> Tab Settings (you may select the very language to replace tabs to spaces. It's cool!) -> Uncheck Use default value and check Replace by space.

There is no 'Edit Components' tab in the preferences setup. You need to go 'Language Menu/Tab Settings', there is an option in there to control tab behavior. You can even set it to work differently depending on the language of the file.

I follow this simple way:

• Double click (Highlight) single tab (ie: \t).
• Press ctrl + F (Find/repace).
• You may not see \t or single tab area on Find What: field. But don't worry.
• Enter a space in Replace With: field.
• Click Replce All .

Done! :)

Note: This method applies to reverse (Replace a space by a tab) case too.

Settings > Preferences > Tab Settings Check the "replace by space". Notice above it there is Tab size: 4 Click on the four and a window will open with the option to change the value to another integer.

Put in your desired integer and press the ENTER key.

There you have it <3.

If you happen to work in a Unix environment, the expand command is what you need:
