How do I convert tabs to spaces in Notepad++?

I found a webpage that suggests it's possible, but I couldn't find any information about how to do it.

I would like to be able to do that, because some web forms don't respect code with tabs in them.

Tab indent = 1x character, Space indent = more than 3x characters. - Yousha Aleayoub
SciTE does this quite easily. Too bad it doesn't extend as well as Notepad++. - bvj
I appear to have entered the Twilight Zone. My Notepad++ is always triple-spacing each tab, and nothing I've updated in the IDE has changed the behavior. I've been using it for years and never ran into this problem before o_o. Even down-grading didn't remove the problem. So yep. I'm calling it. Twilight Zone feature. - kayleeFrye_onDeck
@YoushaAleayoub 1 space = 1 space, 1 tab = different for everyone. - csabinho
@csabinho that's the point. So everyone can customize it and set it to their own size. #Freedom :) - Yousha Aleayoub

To convert existing tabs to spaces, press Edit->Blank Operations->TAB to Space.

If in the future you want to enter spaces instead of tab when you press tab key:

  1. Go to Settings->Preferences...->Language (since version 7.1) or Settings->Preferences...->Tab Settings (previous versions)
  2. Check Replace by space
  3. (Optional) You can set the number of spaces to use in place of a Tab by changing the Tab size field.

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.

I just posted a Notepad++ plugin to convert tabs to spaces. Yes, it converts tabs in the middle of a line. Yes, it takes into account other characters within the tabbed field. Check it out.

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.

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.

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'

Enter image description here

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.

CLR Tabs to Spaces plugin should be a good option. I have used it and it worked.

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! :)

See:

Replace *Tab* by *Space* in <code>Notepad++</code>

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.
