Frequently Asked Questions
Is my text data safe and private?
Absolutely! All text processing happens entirely in your browser using JavaScript. No data is transmitted to any server, ensuring complete privacy and security for your sensitive information.
Can I use multiple cleaning options at once?
Yes! You can enable any combination of cleaning options. The tool will apply them in a specific order to ensure optimal results. For example, it will trim whitespace and remove extra spaces before checking for duplicates.
What happens to the original line order?
By default, the tool preserves the original line order (keeping the first occurrence of duplicates). However, if you enable the "Sort Lines" option, your text will be alphabetically sorted.
Is there a limit to how much text I can process?
There's no hard limit, but very large files (over several megabytes) may cause performance issues depending on your device. For optimal performance, we recommend processing files under 1MB at a time.
Can I use this tool for commercial purposes?
