FAQ

What types of data can the data cleaner handle?

The data cleaner works with any text-based data including CSV, tab-separated values, and plain text lists. It can process data pasted directly into the input field. It handles common issues like extra whitespace, inconsistent capitalization, duplicate rows, and empty lines.

How does duplicate removal work?

The duplicate removal compares each row of your data and removes exact matches. It keeps the first occurrence and removes subsequent duplicates. The tool reports exactly how many duplicates were found and removed so you can verify the results.

Does the tool modify my original data?

No. The tool works on a copy of your data. Your original input remains unchanged in the input field. The cleaned output is shown separately, and you can copy it to your clipboard with one click. You always have both versions available for comparison.

What capitalization options are available?

The tool offers several capitalization modes: Title Case (capitalizes the first letter of each word), UPPERCASE (converts all text to uppercase), lowercase (converts all text to lowercase), and Sentence case (capitalizes only the first letter of each sentence). You can choose the mode that best fits your data.
