Result
This page has no server side at all. The table you paste is parsed by JavaScript inside your own browser, the chart is drawn on a canvas element on your machine, and the export file is assembled locally. Nothing is uploaded, stored or written to any log. You can disconnect from the network after the page has loaded and everything will still work — which is the simplest way to verify the claim yourself.
Facts and limits of this method
| Character affected | The tab character only (U+0009) |
|---|---|
| Default behavior | Each tab is deleted, nothing is put in its place |
| Replace option | Substitutes each tab with exactly one space |
| Consecutive tabs | Each one is handled individually — two tabs become two spaces if replacement is on |
| Spaces and line breaks | Never touched — only tab characters are affected |
| Counter | Always shows how many tabs were found, in either mode |
When it misleads you
- Only tab characters (U+0009) are affected; regular spaces used for visual alignment elsewhere in the text are left completely alone.
- With "replace with space" off (the default), tab-separated columns get glued together with nothing between them — "Name\tAge" becomes "NameAge". Turn the checkbox on if you need to keep a word boundary where the tab used to be.
- Multiple consecutive tabs are each replaced independently: two tabs in a row become two spaces, not one — if you need single-space normalization afterward, run the result through a "remove extra spaces" tool.
- This tool does not touch spaces that already exist elsewhere in the text, so if the source mixed tabs and spaces for alignment, only the tab part of that mix is changed — the spacing may still look uneven afterward.
How it is calculated
The tool scans the text and counts every tab character (U+0009) it finds.
If "replace with space" is off, every tab is deleted outright, with nothing put in its place.
If the checkbox is on, every tab is replaced with exactly one regular space instead of being deleted.
The counter always shows the number of tabs found in the source text, regardless of which mode is selected.
Questions and answers
Why would I use "replace with space" instead of just deleting tabs?
If the tabs were separating values (like columns), deleting them outright glues the values together. Replacing with a space keeps a boundary between them.
Does this affect line breaks?
No, only tab characters are matched. Line breaks and regular spaces pass through unchanged.
What happens with several tabs in a row?
Each one is handled on its own — two consecutive tabs become two spaces (if replacement is on), not a single one.
Will this fix uneven spacing caused by mixed tabs and spaces?
Only partially — it changes the tabs, but any spaces already used for alignment are left as they were, so the layout can still look uneven afterward.
Is my text sent anywhere?
No. Everything runs in your browser; the text is never transmitted.
