It is useful when email addresses are copied from spreadsheets, documents, websites, email messages, CRM systems, databases, or ordinary text and need to be converted into a clean, organized list.<\/p>\n<p>For example, you may have:<\/p>\n<pre><code class=\"language-text\">john@example.com,mary@example.com,peter@example.com<\/code><\/pre>\n<p>and want:<\/p>\n<pre><code class=\"language-text\">john@example.com\r\nmary@example.com\r\npeter@example.com<\/code><\/pre>\n<p>Or you may have:<\/p>\n<pre><code class=\"language-text\">john@example.com mary@example.com peter@example.com<\/code><\/pre>\n<p>and want the same clean list.<\/p>\n<p>You may also receive:<\/p>\n<pre><code class=\"language-text\">john@example.com\r\nmary@example.com\r\npeter@example.com<\/code><\/pre>\n<p>and want them converted into:<\/p>\n<pre><code class=\"language-text\">john@example.com, mary@example.com, peter@example.com<\/code><\/pre>\n<p>The basic idea is to identify the <strong>separator<\/strong> being used and then split or reformat the email addresses accordingly.<\/p>\n<hr
