How to Remove Duplicate Lines Online
Duplicate lines reduce quality in keyword sheets, product feeds, and support exports. This guide shows a fast way to keep one clean version of every line before publishing or importing data.
Use this workflow before clustering keywords, generating briefs, or preparing campaign uploads. A clean source file prevents hidden repetition across your entire publishing pipeline.
Use Cases
- SEO keyword list cleanup before clustering.
- Removing repeated SKUs in ecommerce feed preparation.
- Deduplicating copied meeting notes before summarization.
Step-by-Step Workflow
- Paste the full text list into the editor input panel.
- Choose the "Remove Duplicate Lines" feature from the left sidebar.
- Enable case-insensitive mode when uppercase and lowercase should be treated as the same value.
- Run the feature, review output, and copy the cleaned list to your spreadsheet or CMS.
Expert Tips
- Normalize whitespace first to avoid false uniqueness caused by trailing spaces.
- Sort lines after deduplication so QA review is faster for large files.
