Introduction
テキスト分割は、確認、コピー、処理をしやすいように文章を小さな部分へ分けます。行、段落、文、単語、カスタム区切りを選べます。
1行に1項目のメモ、分かれた段落、カンマや縦棒、タブ、セミコロンを使うリストに便利です。
分割は構造だけを扱い、要約、翻訳、校正、並べ替えは行いません。元の文章を残し、結果を確認してください。
What the tool measures
Line mode follows line breaks, paragraph mode follows separated blocks, and sentence mode follows visible ending punctuation.
Word mode uses a local tokenizer; punctuation, URLs, abbreviations, emoji and scripts without spaces may need review.
A custom delimiter is interpreted literally. Empty segments may be omitted by the processor, so compare important data with the original.
How to use it
- Paste or type the text.
- Choose lines, paragraphs, sentences, words, or custom delimiter.
- Enter the exact delimiter when needed.
- Run the operation and inspect segments in order.
- Check whitespace, punctuation, and empty values.
Splitting method
Mode 1
Lines follow line breaks; paragraphs follow separated blocks.
Mode 2
Sentences and words use visible punctuation and token boundaries; edge cases need review.
Mode 3
A custom delimiter is a literal boundary and surrounding spaces remain when the rule keeps them.

Reading the result
Read the segments in source order and check where spaces or punctuation were placed.
If the result surprises you, test a short sample with one boundary at a time and compare modes.
Common mistakes
Using sentence mode for a list without sentence punctuation.
Entering a delimiter that looks similar but is not identical.
Assuming splitting trims spaces, repairs punctuation, removes duplicates, or preserves every empty field.
Limits
The tool does not rewrite, translate, sort, deduplicate, or verify facts.
Abbreviations, decimals, URLs, emoji, mixed scripts, and languages without spaces may produce unexpected boundaries.
For CSV, code, logs, or signed files, use a format aware parser and test the result in the receiving system.
よくある質問
Which modes are supported?
It supports lines, paragraphs, sentences, words, and a custom delimiter.
What is the difference between lines and paragraphs?
Lines follow line breaks; paragraphs follow separated blocks, often a blank line.
Can I split on a comma or pipe?
Yes. Use custom delimiter mode and enter the exact sequence.
Does the tool remove words or punctuation?
No. It returns segments and does not rewrite the supplied words.
Why did sentences split unexpectedly?
It follows visible ending punctuation; abbreviations and decimals can look like boundaries.
Are empty segments preserved?
They may be omitted. Compare with the original when empty fields matter.
Can I split mixed scripts?
Yes, but inspect direction, punctuation, spaces, and word boundaries.
Is text sent to an AI service?
Splitting uses local rules and does not require an external AI service.
