How does the duplicate removal process work?
Our Remove Duplicates Tool works by:
- First, trimming any leading or trailing whitespace from your input text.
- Splitting your input text into individual "words" based on spaces or other whitespace characters.
- Iterating through these words from start to finish.
- It keeps track of words it has already seen (using a case-insensitive comparison, e.g., "Apple" and "apple" are considered the same).
- Only the first occurrence of each unique word is kept, preserving its original casing and order.
- Subsequent identical words (duplicates) are discarded.
- Finally, the unique words are joined back together with single spaces to form the cleaned text.
Is the duplicate removal case-sensitive?
The tool performs a case-insensitive check when identifying duplicates. This means "Word", "word", and "WORD" are all treated as the same word. However, the tool is smart enough to preserve the casing of the first instance it encounters. For example, if "Word" appears before "word", the output will contain "Word".
Does this tool remove duplicate lines or just words?
Currently, this tool is optimized for removing duplicate words within your text. It processes the text word by word. If you need to remove entire duplicate lines, you might need a different tool specifically designed for line-based deduplication. However, if your lines consist of words and you want unique words across the entire text, this tool will work effectively.
What happens with punctuation and special characters?
Words are separated by spaces. Punctuation attached to a word (e.g., "word." or "word,") is considered part of that word. Therefore, "word." and "word" would be treated as two different unique words. If you want to treat them as the same, you would need to remove punctuation before pasting the text into the tool.
Is there a limit to the amount of text I can process?
Our Remove Duplicates Tool is designed to handle substantial amounts of text efficiently. However, extremely large inputs (many megabytes or millions of words) might be limited by your browser's performance and memory capacity. For most common use cases, you should not encounter any issues.
