Tab to Space & Space to Tab Converter
Tab to Space & Space to Tab Converter: Replaces tab characters (\t) with corresponding number of space characters (U+0020).
About this tab to space & space to tab converter
Replaces tab characters (\t) with corresponding number of space characters (U+0020) Applies Unicode-compliant text transformations and parsing directly in the browser tab without data leakage.
Text processing & transformation mechanics
Parses JSON `{text,size,direction}` and replaces each tab with `size` spaces or each exact run of `size` spaces with a tab. Size defaults to 2; this is not visual column alignment.
Worked text manipulation example
Scenario: Convert a tab to two spaces using JSON.
Sample input:
Processing: Replace each tab literally with exactly two U+0020 spaces.
Illustrative output:
Character encoding & string length boundaries
This is literal replacement, not visual column alignment; size defaults to 2 and has a minimum of 1.
Text formatting and transformations in Tab to Space & Space to Tab Converter preserve character integrity. Check edge cases such as multi-line inputs and special characters before downstream use.
In-memory text processing boundary
String operations and Unicode manipulations in Tab to Space & Space to Tab Converter execute entirely in local browser memory without transmitting input text.
Unicode Consortium & text formatting standards
Unicode Consortium standard annexes (UAX) and character encoding specifications:
- RFC 8259 JSON input syntax and ECMAScript string replacement.
- Local literal tab↔space-run conversion with positive safe-integer size; no tab-stop or visual alignment calculation.

- Replace each tab with size spaces, or each exact run of size spaces with one tab.
- Read the converted text.
Frequently asked questions
How are `size` and `direction` handled?+
A missing, `null`, or blank `size` is 2. Any supplied size must be a finite safe integer; values below 1 become 1. `direction` defaults to `tab-to-space` only when missing, `null`, or blank, and accepts only `tab-to-space` or `space-to-tab`.
How can I convert one tab to two spaces?+
Enter `{ "text": "a\tb", "direction": "tab-to-space", "size": 2 }`. The result is `a b`, with two ordinary spaces between `a` and `b`.
How does `space-to-tab` work?+
It replaces every non-overlapping sequence of exactly `size` ordinary spaces with one tab. With `size: 2`, five spaces become two tabs followed by one space.
Will the result always look aligned?+
No. The tool replaces characters, not display columns. Tab stops, proportional fonts, mixed indentation, and pre-existing spaces can change the visible alignment.
