Gemini space remover

This tool identifies every whitespace character in text copied from Gemini, whether from the chat window or after an Export to Docs, and removes it. Both rendering passes are treated identically, and the resulting mixture of ordinary and non-breaking spaces is handled the same way regardless of source.

Processing runs client-side, in JavaScript, entirely within your browser. There is no upload and no server round trip, and accordingly no run limit.

Gemini frequently answers with bolded lead-ins and nested sub-points, a structure requiring a non-breaking space to preserve visible indentation that plain HTML would otherwise collapse. Export to Docs applies a second rendering pass with its own spacing conventions on top of that, so a value exported and then copied again is not guaranteed to match a copy taken directly from the chat window.

Either path can leave a non-breaking space occupying the position an ordinary space would, indistinguishable on screen and distinct in the underlying bytes. A reply passing through both stages, rendered in chat, exported, then copied, encounters two separate opportunities to acquire one.

A bolded lead-in followed by a colon and a short explanation is a recurring Gemini pattern, and the space immediately following that lead-in is a frequent location for a non-breaking space, since the renderer keeps the bold text and its adjacent punctuation visually attached.

Viewed in a plain-text editor, the line appears entirely ordinary. Compared character by character against a hand-typed equivalent, the comparison fails at precisely that position, with nothing visible to account for the discrepancy.

A deeper level of nesting can carry more than one non-breaking space in a row, one for each indentation step the renderer needs to preserve, so a third-level sub-point can carry two or three stacked together rather than a single one. Removing every space handles that correctly in one pass, where a find-and-replace built to catch one at a time would need running repeatedly.

No configuration required.

Step 1

Paste the text from Gemini's chat window or an exported Doc into the input field.

Step 2

Run the removal. It executes instantly, locally.

Step 3

Read the result, a single unbroken string.

A dedicated remover outperforms a plain find-and-replace because the space bar produces exactly one character, while several others render identically and evade a search for it.

Regular spaces

The standard space bar character, U+0020.

Non-breaking spaces

Frequently present around Gemini's list indentation and within Docs-exported content.

Tabs and line breaks

Tab characters, carriage returns and newlines.

Unicode spaces

Thin and hair spaces occasionally left at formatting boundaries.

Ideographic space

The full-width space used in Chinese, Japanese and Korean text.

A value pasted into a Sheets formula fails to match an identical-looking cell when a non-breaking space occupies the position the formula expects an ordinary one. A slug generated from a Gemini-written heading resolves to an unintended address.

A non-breaking space carried through a Docs export can additionally invalidate a CSV import or a database key that appears correct on screen.

A find-and-replace operation performed within the exported Doc itself can fail identically: a search for an ordinary space locates every gap except the one requiring correction.

The output is a single continuous string with no gaps, appropriate for a slug, a key, or a field that rejects whitespace outright.

To retain single spaces between words while collapsing only runs of two or more, use the whitespace minifier instead. To rejoin broken lines into a paragraph, use the Gemini line break remover.

Analysts building a Sheets formula from values pasted out of Gemini or a Docs export run this to catch a non-breaking space before it silently breaks a match.

Engineers pulling identifiers or configuration values out of Gemini's output run this before committing them, and anyone constructing slugs or keys from Gemini-drafted headings relies on it because those fields reject whitespace outright.
