Extract emails, URLs, phone numbers, or any custom regex pattern from CSV columns into a new structured column.
Free for files up to 5 MB and 10,000 rows. Files are processed in your browser — nothing is uploaded to a server. No account required.
Pull structured values out of messy free-text columns. Choose a column, give a regular expression, and every match in each cell is written into a new column, comma-separated where a cell contains more than one match.
The presets cover what people ask for most: email addresses, URLs, phone numbers, plain numbers and IP addresses. A support ticket export with the customer address buried in a notes field, or a server log column where you only want the IP, is a single click with those. Anything more specific is a matter of typing your own pattern.
Results update as you type, so an expression that matches nothing is obvious straight away. Name the new column before downloading so the header still means something downstream.
