Use the Date Extractor
Paste text containing dates into the input area. Choose an Output mode to show the matches as List, rewrite the text with Harmonize, view a Table, or create CSV or JSON output. The result area provides Copy and Download controls.
Choose an output mode and date format
Use Date format to choose ISO 8601, US, EU, EU dot, Long, Long day-first, Short, or Custom.... If you choose Custom..., enter a value in Custom pattern (YYYY, MM, DD, MMMM, MMM, D, Do). Table view uses the headers Context, Found, and Normalized.
How to extract and format dates

Review results and limitations
Review the result and date count after processing. The page does not document the complete recognition grammar, file types, file-size limit, no-match behavior, invalid-date behavior, or CSV cell parsing. Review important results before using them elsewhere.
The page describes processing as browser-side JavaScript. It does not establish an absolute privacy guarantee or document all network behavior, so follow your own data-handling requirements for sensitive text.
Frequently Asked Questions (FAQs)
What date formats are supported?
The interface provides output-format examples for ISO 8601, US, EU, EU dot, Long, Long day-first, Short, and Custom.... The exact date-recognition grammar is not listed on the page, so review the results after processing.
What does Harmonize mode do?
Harmonize rewrites the original text by replacing detected dates with formatted values. Choose the required output in Date format before reviewing the rewritten text.
Is my data safe when I paste it here?
The page describes processing as browser-side JavaScript. The interface does not state accepted upload types, file-size limits, or the behavior of other network requests, so review your organization's requirements before using sensitive material.
How are two-digit years interpreted?
For an ambiguous numeric date, use Interpret ambiguous numeric dates as DD/MM when the day-first reading is required. Review two-digit-year results before reuse because the page does not document a year-mapping rule.
Can I use this to clean a CSV column with mixed date formats?
You can paste CSV text into the input area and choose CSV, JSON, List, Harmonize, or Table output. The page does not document CSV cell parsing or guarantee that every cell will be rewritten, so check the result before reuse.
