Text Cleaner (Remove Accents and Duplicate Lines)

You paste a text or a list (one item per line) and choose what to do with it by checking the options you want. The cleanup happens in real time, and the result is ready to copy, with a line count before and after.

The available operations are:

• Remove accents — swaps accented letters for their unaccented equivalents (á becomes a, ç becomes c), keeping the rest of the text.
• Remove duplicate lines — keeps only the first occurrence of each repeated line.
• Remove blank lines and collapse spaces — clean the text of empty lines and of extra spaces at the start, end or middle.
• Sort lines — arranges everything alphabetically.

The operations combine: you can, for example, remove accents, drop duplicates and sort all at once. Everything is processed in the browser, without sending the text to any server.

Cleaning lists is a task that comes up constantly. When merging emails or names from several sources, it's common to end up with duplicates and blank lines — removing those leaves the list ready to use. Before importing data into a spreadsheet or system, stripping accents avoids encoding problems in fields that only accept simple characters.

Developers use it to generate identifiers and file names without accents; marketers, to clean contact lists; students and researchers, to organize references and notes. Whenever you have a messy block of text and want it clean and organized, it's sorted here in seconds.

One thing to watch is the order in which the operations make sense. Removing duplicates before trimming spaces can let through lines that are "the same" but have different trailing spaces. The tool trims spaces before comparing, precisely to catch those cases — but it's worth checking the result when the list is sensitive.

Another caution is removing accents from text that will be read by people. Stripping accents is great for file names and systems, but it leaves text incorrect for reading. Use that option for technical data, not for final content meant for the reader.

There's also the confusion between a duplicate line and a similar line. The removal treats only identical lines as equal. "Anna Smith" and "anna smith" are treated as different because of the capitals — something to consider if your list mixes formatting.
