Text cleanup
Remove duplicate lines and clean text safely
Clean pasted lists, repeated rows, line breaks, and casing issues without losing useful information.
Decide what counts as a duplicate
A duplicate line can be obvious in a keyword list, but less obvious in logs, customer notes, or event exports. Decide the rule before cleaning.
- Trim whitespace first.
- Choose case-sensitive or case-insensitive review.
- Keep original order if it matters.
Quick workflow
Remove line breaks if the text pasted badly, then remove duplicates, then normalize case only when casing is not meaningful.
Do
- Keep a copy of the original.
- Review the removed items when the data matters.
- Use cleanup tools on small batches first.
Don't
- Do not remove duplicates from transaction or log data without context.
- Do not change case when names or codes are case-sensitive.
- Do not overwrite the only copy.
FAQs
Can duplicate removal lose important data?
Yes. If repeated lines represent real repeated events, removing them can change the meaning of the data.
Should I remove line breaks before duplicates?
Only when line breaks are accidental. If each line is a record, keep the line structure.
