About this tool

About List Tools

Working with lists of items is a common task for developers, system administrators, and data analysts. Sorting a list of domains, removing duplicate entries from a CSV column, filtering lines that match a pattern, or converting a comma-separated string into separate lines are all operations that take seconds in a dedicated tool but minutes to script from scratch. List Tools brings these operations together in one place.

How to use

Paste a list of items, one per line, into the input area. Select an operation from the toolbar: Sort arranges lines alphabetically; Dedupe removes repeated lines and reports how many were found; Shuffle randomises the order; Number prefixes each line with a counter; Reverse flips the list top-to-bottom; Filter keeps or removes lines matching a plain string or regular expression; Join/Split converts between newline-separated and delimiter-separated formats. Click Apply to run the selected operation.

Use Sort and Dedupe together to clean up a list of hostnames or email addresses before importing into a tool. Use Filter with a regex to extract lines matching a specific pattern such as lines containing an IP address or a domain suffix. Use Join to convert a newline list into a comma-separated value for pasting into a SQL IN clause or a config file.
