Clean and transform lists line by line with one click. Sort, dedupe, trim, shuffle, and add line numbers to prepare data for any workflow.
How to use this Text Line Processor effectively?
Paste your list into the input box, making sure each item sits on its own line. Use the operation buttons to apply the transformation you need: sort ascending or descending, sort by length, reverse or shuffle, remove duplicates or empty lines, and trim whitespace. If you need references for audits or QA, add line numbers and then remove them later when exporting. The output updates immediately, so you can chain operations by copying the result back into the input for a second pass. For example, trim first, then remove empty lines, then deduplicate, and finally sort. This step-by-step approach keeps your data consistent and prevents subtle formatting issues before importing into a spreadsheet, database, or CMS.
Why use an online Text Line Processor?
A browser-based line processor is the fastest way to clean lists without opening a spreadsheet or writing scripts. It is perfect for quick tasks like sorting keyword lists, cleaning CSV snippets, or deduplicating log entries. Because everything runs locally in your browser, sensitive items like internal IDs or customer lists stay private. The tool also standardizes common operations into buttons, which reduces mistakes and saves time compared to manual editing. Whether you are a developer, analyst, or content manager, you can process text in seconds and hand off clean results to the next step.

Common line-processing workflows
Use this tool to clean email lists before sending campaigns, remove duplicate tags from a CMS, or sort product SKUs for quick checks. When working with logs, shuffle and dedupe error messages to focus on unique patterns. For localization and content reviews, add line numbers to track changes across versions, then remove them for final delivery. If you are preparing data for scripts or imports, trimming and removing empty lines prevents parsing errors. These small workflows add up to major time savings when you regularly handle text data.
FAQ
Q: Does deduplication keep the original order?
A: Yes. The dedupe action keeps the first occurrence and removes later duplicates, preserving the original line order.
Q: Can I chain multiple operations?
A: Yes. Apply one operation, then copy the output back into the input to run another. This is useful for trim → remove empty → dedupe → sort workflows.
Q: Is my data uploaded?
A: No. All processing happens locally in your browser, so your data never leaves your device.
