Extract text inside square brackets from notes, tags, citations, logs, and structured drafts. Detect nested brackets, empty brackets, duplicate bracket content, and export clean extracted values.
START|END.This tool finds text between brackets patterns in raw text and turns them into a clean, reusable list with validation signals, duplicate counts, and export-ready structure.
Strict mode favors clean output. Standard mode is better when discovering unusual formats in copied pages, logs, OCR, or mixed technical text.
Input:Task [urgent] assigned to [team A]. Citation [source: [internal]]. Empty [] and repeat [urgent].
Output: extracted matches with total count, shown count, duplicate count, quality score, and export buttons.
The tool uses browser-side extraction rules tuned for the selected pattern. It reports match volume, unique results, duplicate reduction, scanned lines, scanned characters, and practical classification signals.
Pattern extraction cannot verify every real-world edge case semantically. Review critical security, legal, billing, or compliance outputs after export.
Paste the source text into the input area and run the extractor. The tool scans locally, lists matching text between brackets, and shows counts, duplicates, and export options.
Yes. Keep remove duplicates enabled to show each extracted value once while the result card still reports total matches and duplicates.
Yes. Use the CSV or JSON download buttons to save the extracted data for spreadsheets, audits, reporting, or developer workflows.
Strict mode filters malformed, empty, or risky matches so the final output is cleaner. Disable strict mode when you need broader discovery.
No. Processing happens in your browser. Your pasted text is handled locally unless you choose to copy or export the result.
