whitespace cleanup が重要な理由

画面では fine な text が paste 先で fail。email double space after period；Word/Docs non-breaking space search 不可；PDF copy で文ごと行；code trailing tab choke；CMS invisible zero-width reject。

この tool が clean するもの

余分 space/tab

Remove extra spaces ordinary space/tab run を line 内 single space collapse。line break は blank-line option 除非。Trim trailing end-of-line junk code diff/scraped HTML。Trim leading indentation remove — source code compile 必要なら off。

Convert tabs spaces width 2/4/8 expand。Convert spaces tabs leading indent only sentence space 不変 prose readable code indent marker consistent。

NBSP と Unicode gap

Replace NBSP U+00A0 Word same-line two words → ordinary space。Normalize thin/figure/ideographic Unicode whitespace variant identical eye find-replace CSV strict validator break。

normalize 後 still misbehave — Text Character Cleaner punctuation/emoji/control whitespace intentionally leave。

Zero-width：safe vs aggressive

Safe zero-width space U+200B BOM remove most paste disaster common invisible junk。Aggressive also zero-width joiner/non-joiner Arabic/Persian/Urdu/Indic script letter shape — Latin-only known spam marker certain only aggressive。

multilingual writer WriteWithin safe default。URL/DB field break catch reader depend script joiner touch しない。

PDF line break と blank line

Fix PDF line breaks hard-wrapped mid-sentence academic/legal PDF classic。lowercase next line start merge space collapse trim tidy。

Collapse blank lines empty row single gap email forward ideal。Remove blank lines entirely。list dedupe/sort Line Tools whitespace-only row blank stricter list hygiene。

不可視文字を表示

Show invisible preview space(·) tab(→) NBSP(⍽) zero-width output pane。Copy cleaned without marker — diagnosis not export。colleague「paragraph OK」preview on hidden obvious。

処理順（固定 pipeline）

1. Strip BOM file start
2. Remove zero-width safe/aggressive
3. Replace NBSP normalize Unicode space ordinary
4. Normalize line endings internal
5. Optionally join PDF hard line break
6. Trim leading/trailing space per line
7. Collapse repeated space/tab or remove all space
8. Blank-line collapse/removal
9. Convert tabs↔spaces restore chosen line-ending

order fixed reason：PDF join before space collapse merged sentence single space not double gap。

common paste source Preset

• Email paste — collapse space replace NBSP collapse blank line
• Word / Docs — email same office-document spacing tuned
• PDF text — hard line-break repair on space normalization
• Code indent — tabs spaces trailing trim LF no space collapse inside line
• CMS / scraper — trim both ends every line collapse space LF

Whitespace vs related tool

Character Cleaner letter/number/emoji/punctuation/symbol remove or keep class specify。Unicode NFC/NFKD script-aware accent strip。problem which character exist not space count between word。

Line Tools whole line dedupe/sort/filter keyword join paragraph split width。structure not intra-line spacing。chain Whitespace first Line Tools dedupe contact list common。

Line Counter measure no change。Case Converter URL Cleaner casing/link hygiene orthogonal spacing。

step-by-step messy paste clean

1. Whitespace Cleaner open input paste
2. preset source Email Word PDF Code CMS
3. Show invisible suspicious
4. output stats characters removed line count preview scan
5. cleaned output copy destination

common mistake

• Arabic/Hindi aggressive zero-width — safe unless joiner unnecessary know
• Indented code trim leading — Code preset or leading trim off
• Deduplication expect here — duplicate line Line Tools
• Smart quote remove here — character-level Character Cleaner
• Collapse twice tools — one pipeline pass enough

in-browser whitespace benefit

• No account upload text device
• Deterministic pipeline same input option same output
• Multilingual-safe zero-width other remover skip
• Live stats characters/lines changed
• Chromebook borrowed laptop locked corporate browser

common question

Arabic/Hindi break? Safe zero-width only zero-width space BOM。Aggressive joiner some script need — sure only。

See invisible before delete? Show invisible marker output copy clean without marker。

Text uploaded? No browser entirely。

Count line after? Line Counter cleaned text submission limit verify。

Normalize before/after case? Whitespace first Case Converter hidden space casing uneven。
