Remove Duplicate Lines

Duplicates hiding in a long list

You combined email addresses from two sign-up forms, phone numbers from two spreadsheets, or keywords from several tools, and now some lines appear two or three times. Spotting them by eye in hundreds of lines is tiring, and you always miss a few. Jood's tool keeps the first occurrence of every line, removes the repeats and leaves the original order untouched.

How to use it

1. Paste your list, one item per line.
2. Pick the options you need.
3. Click "Start Now", then "Copy Result".

Above the result you see how many duplicate lines were removed and how many lines remain.

The three options

• Ignore spaces at the start and end of lines: on by default, because one invisible space is enough to make two identical lines look different to a computer.
• Ignore letter case: turn it on for emails and names, so [email protected] and [email protected] count as the same line. Without it, both stay.
• Remove empty lines: without it, the first blank line is kept and any later blank lines are dropped as duplicates.

The tool only catches identical lines. "John Smith" and "John Smith" with two spaces in the middle, or "Jon" and "John", stay as separate lines. The original order is kept too, so if you want the list in alphabetical order, sort it afterwards in Excel or Google Sheets.

When you will need it

• Cleaning a mailing list before a bulk send, so nobody gets the same email twice.
• Merging two customer lists from different years.
• Tidying keywords gathered from several research tools before putting them in a spreadsheet.

Afterwards you can count what is left with the line counter, or turn the list into a single comma-separated line with the comma separating tool.

Where your list goes

The list is sent to Jood's server, processed, and the result appears on the same page. It is not kept afterwards. Even so, avoid pasting confidential data into any online tool.
