Frequently Asked Questions

• Q: What input formats are supported?
• A: This tool supports plain text input. You can directly paste any text content containing email addresses (such as articles, code, log files, etc.) into the "Content to extract" area for processing.
• Q: What is the output format?
• A: The output is in plain text format. Each successfully extracted valid email address will be displayed on a new line. If the "Show Statistics" function is enabled, the first line of the result will additionally display the total number of extracted emails.
• Q: How does the tool determine if an email address is valid?
• A: This tool matches email addresses based on industry-standard regular expressions, recognizing addresses that include the "@" symbol, valid domain structures (e.g., `example.com`) and other features. Strings that do not conform to basic email format specifications (e.g., `user@@test.com` or `not-an-email@com`) will not be extracted.
• Q: Can I batch process a large amount of text content?
• A: Yes, this tool is designed to efficiently process large amounts of text. You can paste long texts containing hundreds or even thousands of email addresses at once, and the tool will quickly complete the extraction and present the results.

Important Considerations

• Input Content: Please ensure that you paste plain text content. This tool cannot directly process email addresses in images, PDFs, or binary files.
• Format Matching: Although this tool uses powerful regular expressions, it may not accurately identify a very small number of unconventional or non-standard email address formats that do not conform to universal international standards.
• Privacy and Security: This tool does not store or record any content you input. For personal information protection, it is recommended that you avoid processing extremely sensitive or confidential data.
• Statistics Function: The "Show Statistics" option only adds a total count line to the output and does not affect the actual email address extraction logic.
