  • Remove duplicate numbers with one click
  • See a total count of extracted values

⭐ How to Use It

⭐ Why Use Find Numbers?

  • Data preparation: Quickly gather all numeric values for spreadsheets or databases
  • Reporting: Pull figures from reports, receipts, or copied web pages
  • Audits: Verify amounts, counts, or percentages without manual scanning
  • Development: Test or extract numbers from logs and source code

⭐ Advanced Options

  • Include/exclude percentages: Choose whether percent signs are treated as part of the number
  • Currency-aware: Optionally strip currency symbols or keep them as part of the extracted token
  • Preserve context: Show the line or snippet where each number was found to help verify results
  • Numeric sorting: Sort numerically rather than lexicographically (so 10 appears after 2)

⭐ Tips for Best Results

  • Remove unrelated boilerplate (navigation, footers) before extracting to avoid noise.
  • Use the "preserve context" option if you need to verify where each number came from.
  • If numbers use commas as thousands separators (1,000), ensure your settings handle them correctly.
