1. Choose this workflow

Remove repeated entries in a line-based list while retaining the first occurrence and original order.

2. Prepare your input

Put one entry on each line. Decide whether case and trailing spaces are significant; exact comparison preserves those differences.

3. Follow a worked example

apple, banana, apple on three separate lines becomes apple followed by banana.

4. Check the result

Compare the output with the example and original. Check punctuation, case, spacing, line order and identifiers where relevant. Use the available copy or download action and inspect the result in the receiving application. Retain the source until the change is verified.

5. Are differently capitalized or padded lines duplicates?

No. Comparison is exact: Apple, apple, and apple followed by a space are different. Trim lines or convert case first if you want those differences removed.

6. Recover from an error

Try the small example first. Read the error message and check syntax and the selected operation. If output differs from your intention, return to the original and change one setting at a time. Formatting and conversion do not validate the meaning of data.

Start with a small example and check the result before using your own data.
