About this tab to space & space to tab converter
Tab to Space & Space to Tab Converter — browser-based utility.
How this tool works
Implements client-side Tab to Space & Space to Tab Converter operations. Replaces tab characters (\t) with corresponding number of space characters (U+0020) specifically designed for a developer converts tabs to 2 spaces (or spaces to tabs) to meet project code style guidelines.
- Invisible Codepoint Detection: Scans character codepoint ranges against Unicode formatting categories (Cf, Cc), highlighting hidden characters.
- Unicode Normalization: Applies selected normalization form (NFC canonical composition, NFD decomposition, NFKC/NFKD compatibility).
- Pangu Spacing Heuristics: Evaluates character-pair boundaries via regex lookaheads, injecting half-width spaces between CJK ideographs and alphanumeric ASCII.
- Whitespace Collapsing: Cleans repeated spaces, trailing line spaces, and redundant blank lines according to user settings.
Worked example
Scenario: A developer converts tabs to 2 spaces (or spaces to tabs) to meet project code style guidelines.
Sample input:
Processing: Replaces tab characters (\t) with corresponding number of space characters (U+0020).

Limits and verification
Does not alter intentional whitespace within code blocks when code-preservation mode is selected. Carefully preserves directional formatting markers (RLM/LRM) when bi-directional Arabic/Hebrew text is explicitly preserved.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How does Tab to Space Converter determine the width?+
It reads a JSON size value, converts it to a number, and uses at least one space; an absent or falsy size defaults to two. In tab-to-space mode, every tab becomes that many ordinary spaces.
What did the browser fixture verify?+
With text a tab b, direction tab-to-space, and size 2, the rendered output was a followed by two spaces and b.
How does space-to-tab mode work?+
It replaces each non-overlapping run of exactly the selected number of ordinary spaces with one tab. Partial runs and runs affected by earlier replacements are not column-aware.
Does it preserve visual alignment in every font?+
No. It replaces characters only. Tab-stop rendering, proportional fonts, mixed indentation, and existing groups of spaces can change the visual columns.
