A list is not always one item per line; it may be separated by commas or semicolons instead.
Remove Duplicates from List lets you choose the separator, then removes repeated items and rejoins them.
How to use Remove Duplicates from List
- Paste your list, separated by lines, commas or semicolons, into the input box.
- Choose which separator your items use, and Remove Duplicates from List drops repeated items.
- Copy the cleaned list, or download it as a text file.
Use cases
- Deduplicating a comma-separated list of tags.
- Cleaning a semicolon-separated field of values.
- Removing repeats from a list however it is delimited.
Good to know
Remove Duplicates from List splits the input on the separator you choose, line breaks, commas or semicolons, trims each item, removes repeats keeping the first, and rejoins the unique items with the same kind of separator. A readout shows how many items remain.
Frequently asked questions
What separators are supported?
You can treat items as separated by line breaks, commas or semicolons, selected from the control.
Are items trimmed before comparison?
Yes. Each item has its surrounding spaces removed so spacing differences do not create false uniques.
How are the unique items returned?
They are rejoined using the same separator you selected, so a comma list stays a comma list.
