Text converter

This tool takes pasted text, commonly output from a chat assistant, a PDF export or a word processor, and normalizes its formatting. Hidden Unicode characters are always removed, and three independent toggles control whether it also normalizes spacing, collapses excess blank lines, and straightens curly quotation marks and long dashes into plain ASCII.

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

Text copied from a chat window, a PDF export or a word processor rarely arrives in a clean state. It commonly carries doubled spaces, runs of three or more blank lines, curly quotation marks and long dashes inconsistent with a plain-ASCII house style, and invisible Unicode characters introduced by whatever rendered the text before it was copied.

None of this is apparent on inspection. The text reads correctly until it reaches a system that parses it strictly: a markdown renderer, a CMS field, a script expecting a specific punctuation convention.

The inconsistency is rarely uniform across a single document either. A block pasted from a chat window frequently sits beside a paragraph pasted from a PDF, producing two distinct quote styles and two distinct spacing conventions within the same page, exactly the condition this tool is designed to normalize.

Each toggle is independent, so only the transformations you select are applied.

Step 1

Paste the text into the input field.

Step 2

Select which options to apply: normalize spaces, collapse blank lines, straighten quotes and dashes.

Step 3

Run the conversion and read the result.

Hidden Unicode characters are removed unconditionally. The remaining three options are independent:

Normalize spaces

Reduces runs of two or more spaces or tabs on a line to one, and trims trailing whitespace at each line's end.

Collapse blank lines

Reduces three or more consecutive blank lines to a single blank line, preserving paragraph structure without excess gaps.

Straighten quotes and dashes

Converts curly opening and closing quotation marks to straight equivalents, and converts em and en dashes to a plain hyphen.

Hidden character removal executes first, since a stray invisible character embedded within a run of spaces would otherwise interfere with the subsequent spacing pass. Space normalization and blank-line collapsing follow, and punctuation straightening runs last, once the visible structure of the text is finalized.

This sequencing is internal to the single-pass conversion and requires no configuration, but it accounts for consistent output even on input carrying several distinct categories of formatting inconsistency simultaneously.

A curly apostrophe pasted into a script expecting a straight one produces a syntax error rather than a cosmetic issue. A run of doubled spaces defeats a string comparison expecting single-spaced input. A hidden character in the same text can invalidate structured data or cause a find-and-replace to silently fail against text that appears identical.

None of this is visible from reading the text; it surfaces only once something parses it strictly.

No. This tool operates exclusively on formatting: whitespace, blank lines, hidden characters and, when selected, quote and dash style. Every word is returned exactly as written, in the original order.

A task requiring different wording, a paraphrase or a tone change, requires a different category of tool, one that transmits text to a server for rewriting. This tool does not do that, and any tool on this site that does states it plainly.

Editorial teams run this as a final pass before publishing, to catch stray spacing and invisible characters left behind by whichever tool produced the draft.

Engineers convert curly punctuation into plain ASCII before pasting text into a script or configuration file, where a typographic quote would otherwise break parsing, and editors use the blank-line collapse when assembling a document from multiple pasted sources.
