Practical Examples
Sorting Alphabetically
Cleans up duplicate email lists, database IDs, or word entries.
Input:
banana apple banana
Output:
apple banana banana
Common Mistakes & Troubleshooting
- Ignoring hidden whitespace: a line with "apple " is different from "apple" unless extra spaces are trimmed first.
- Numeric sorting vs alphabetical: "10" comes before "2" in alphabetical sorting. Select "Numeric (0-9)" to sort numbers correctly.
Frequently Asked Questions
Does removing duplicate lines preserve the original line order?
Yes! FormatFlow retains the very first occurrence of each unique line and preserves its original position in the list.
Are empty lines counted in total lines?
Yes. FormatFlow shows both total lines and non-empty lines separately, allowing you to easily gauge whitespace.
