Sentence Splitter & Extractor

Splitting text into sentences looks like a job for one regex: break on periods. That breaks the moment an abbreviation shows up, because "Dr. Alvarez" reads like two sentences to a naive splitter. Sentence Splitter & Extractor holds a bundled list of roughly 30 short forms (Dr., Inc., a.m., Corp. and similar) and re-merges any fragment that ends on one before it counts as a break.

That gets you a clean list of sentences, and the tool goes one step further. Filter the result by a minimum or maximum word count, or by a keyword, before you export it. An editor pulling a pull-quote, a student isolating topic sentences for an outline, or someone auditing a report for run-on sentences can narrow a forty-sentence page down to the three that actually matter.

Worked Example: Splitting a Real Paragraph

Click Load Sample to load six sentences about a finance-team meeting, opening on "The finance team met with Dr. Alvarez before the 9 a.m. review." Despite the period after "Dr.", the splitter keeps that clause attached to what follows it and reports 6 sentences total, not seven. Switch Output format to JSON array and the same six strings come back as a valid array, ready to paste into a script.

Every sentence, matched or not, stays visible in the expandable View all 6 detected sentences panel underneath. The ones a filter excludes render dashed and dimmed instead of disappearing, so you can see what got cut and why.

What Happens When Punctuation Gets Weird

• Quoted dialogue like "These numbers don't add up," she said. stays one sentence: the comma inside the quotation marks isn't sentence-ending punctuation, only the period after "said" is.
• A trailing abbreviation with nothing after it, at the very end of your pasted text, still gets returned rather than silently dropped. There's no next fragment to merge it with, so it ships as its own final sentence.
• Paste text with no period, question mark, or exclamation point anywhere and the tool shows exactly what's wrong: "No sentences detected — try adding a period, question mark, or exclamation point."

Format Notes on the Four Export Shapes

One per line is the default and pastes cleanly into a spreadsheet column. Numbered list prefixes each sentence with its position, useful for citing "sentence 4" in a review comment. JSON array quotes and escapes each string so it drops straight into a test fixture or a script. CSV column wraps every sentence in double quotes and doubles any internal quote character, so a sentence that itself contains a quotation mark still parses correctly in Excel or Sheets. Input over 50,000 characters is rejected outright, with a message that reads "Input exceeds 50,000-character limit." rather than silently truncating mid-sentence.
