Convert spaces into tabs

This tool converts spaces into tabs in your text. It offers flexible conversion modes so you can: • Replace every occurrence of two or more consecutive spaces with a single tab. • Replace a fixed number of consecutive spaces (as specified by you) with a tab. • Replace only leading indentation spaces with tabs, leaving inline spacing intact. • Replace space sequences with a custom format (using a placeholder). Simply enter your text, choose the desired conversion mode and settings, and click the process button.

Conversion Modes:

Convert All Sequences of Spaces to a Single Tab
Replaces every occurrence of two or more consecutive space characters with a single tab character.

Convert Fixed Number of Spaces to a Tab
Replaces every occurrence of a fixed number of consecutive spaces with a tab character. Enter the number of spaces to replace (e.g., 4).

Convert Leading Indentation Spaces to Tabs
Converts only the spaces used for indentation at the beginning of lines into tab characters, leaving inline spaces unchanged.

Convert Spaces with Custom Format
Replaces space sequences with a custom format string. Use {tab} as a placeholder for the tab.

Examples:

Convert All Sequences of Spaces to a Single Tab

Every sequence of two or more spaces is replaced by a single tab character.

Before:

Hello   world!  This is a test.

After:

Hello	 world!	This is a test.

Convert Fixed Number of Spaces to a Tab

Every occurrence of exactly the specified number of spaces is replaced with a tab. (e.g., 4 spaces become a tab)

Before:

Indentation:     function test() { }

After (spaceCount = 4):

Indentation:	 function test() { }

Convert Leading Indentation Spaces to Tabs

Only the leading spaces (used for indentation) at the beginning of each line are converted to tabs.

Before:

    function test() {
        return true;
    }

After:

	function test() {
		return true;
	}

Convert Spaces with Custom Format

Replaces every sequence of two or more spaces with the custom format string. For example, if you specify "[{tab}]", it will replace each sequence with that string.

Before:

Hello   world!

After (Format "[{tab}]"):

Hello[{tab}]world!
