Frequently Asked Questions
What part of the email address does this tool extract?
This tool extracts the username or local part of email addresses - everything before the @ symbol. For example, from 'john.doe@company.com', it would extract 'john.doe'. This is useful for creating user accounts, analyzing naming patterns, or processing contact lists.
Can I process multiple email addresses at once?
Yes! You can input multiple email addresses separated by commas, spaces, or line breaks. The tool supports auto-detection of your input format, or you can manually specify how your emails are separated. It can handle hundreds of email addresses efficiently.
Does the tool validate email addresses before extracting usernames?
Yes, when email validation is enabled (default), the tool checks each email address for proper format before extracting the username. Invalid emails are skipped and reported in the statistics. This ensures you only get usernames from legitimate email addresses.
What output formats are supported?
The tool supports multiple output formats: plain text list (one username per line), formatted list with bullet points, JSON array format for programming use, and CSV format for spreadsheet applications. You can choose the format that best fits your workflow.
How does duplicate removal work?
When duplicate removal is enabled, the tool identifies usernames that appear multiple times in your input and keeps only unique entries. For example, if you have both 'john@company.com' and 'john@example.org', it will only show 'john' once in the results, along with a count of duplicates found.
