Is my data safe when I use this tool?

Definitely. All processing happens directly in your browser, so your text is never sent to a server. Your data stays on your device, ensuring complete privacy.

Can I use this tool without an internet connection?

No, it's a web-based tool, so you need an internet connection to access it. However, it's lightweight and loads quickly even on slower connections.

Does the tool handle different types of text, like CSV data?

Yes, as long as the data is in plain text format, the tool will process it. It works with CSV, TSV, and any other text-based data.

What happens if I have blank lines in my text?

Blank lines are treated as duplicates of each other, so only one blank line is kept. If you want to remove all blank lines, you can do that separately, but the tool focuses on duplicate lines.

Tips and Best Practices

• Before you run the tool, make sure your text is in plain text format. Rich text with formatting can cause unexpected results.
• If you're working with case-sensitive data, remember that the tool treats "Apple" and "apple" as different lines. Check your data for case inconsistencies first.
• Use the tool on a copy of your original data, just in case you need to reference the original later. It's a good habit to keep a backup.
• For large datasets, it's a good idea to run the tool a couple of times to ensure no duplicates slipped through, especially if you've added new lines since the last run.
• If you're cleaning a list for a mailing campaign, also look out for extra spaces at the beginning or end of lines. The tool won't catch those, so you might want to trim whitespace separately.
• Combine this tool with other text utilities on toolvex.com for a complete workflow – like sorting lines or removing blank lines – to get your text exactly how you want it.
