Date Extractor

The Date Extractor scans any block of text you paste and pulls out every date it can recognise, covering ISO dates like 2026-01-05, slash and dotted numeric formats, and written styles such as January 5, 2026 or 5 Jan 2026. Instead of reading through documents to note when things happened, you get a tidy table that pairs each date with the format it was written in, ready to review or export in seconds.

It is built for analysts, researchers, editors, and developers who work with mixed text that contains dates in inconsistent styles. Because the tool labels each match with the format it matched, you can quickly see how many different date conventions appear in a document, which is invaluable when you are cleaning data or deciding how to standardise a set of records.

Everything runs locally in your browser using JavaScript, so nothing you paste is uploaded to a server or stored anywhere. Paste your text, toggle deduplication and sorting, and the finished table appears instantly along with a statistics panel showing how many dates were found and returned across all the supported formats.

Features

• Recognises ISO dates in the YYYY-MM-DD format used by databases and technical documents.
• Detects numeric slash, dotted, and dashed dates covering common US and European conventions.
• Matches written dates such as January 5, 2026 and 5 Jan 2026, including abbreviated month names.
• Labels every match with the format it matched so you can audit inconsistent date styles.
• Avoids counting the same date twice when it overlaps between two similar patterns.
• Removes duplicate dates and offers optional sorting so the table stays clean and scannable.
• Shows a stats panel counting dates found, dates returned, and duplicates removed.

How to use Date Extractor

1. Paste the document, export, or notes that contain dates into the input box.
2. Toggle Remove duplicates to collapse repeated dates into a single row where you prefer.
3. Toggle Sort A to Z if you want the table ordered by the date text for easier scanning.
4. The extracted date table updates live as you paste or change any option.
5. Review the Format column to see which conventions appear across your text.
6. Export the table to CSV or copy it to your clipboard for use in a spreadsheet.

Benefits

• Helps analysts audit how many date conventions appear in a document before standardising them.
• Lets researchers pull a timeline of dates out of long text without reading every line.
• Gives editors a quick way to spot inconsistent date styles across a manuscript or report.
• Keeps output clean from the start with built-in deduplication and optional sorting.
• Processes confidential documents safely because nothing you paste ever leaves your device.
• Gives instant, transparent feedback through counts so you can trust the extraction result.

This tool is most useful when a document mixes date formats and you need to see them all at once. Common sources include exported reports, scraped web content, meeting notes, and data files with free-text date columns. Because each match is labelled with the format it matched, the table doubles as a quick audit of how consistent your dates are, which is a great first step before cleaning or normalising the data.

The extractor matches the shape of a date rather than validating the calendar, so an impossible value such as 2026-13-40 that follows the ISO structure could still be captured. It also cannot resolve whether a numeric date like 03/04/2026 means March 4th or April 3rd, since that depends on the source convention. Use the format labels as a guide and confirm ambiguous numeric dates against the context of the original document.
