Frequently Asked Questions
- Does this tool work with large lists?
- Yes, our algorithm is optimized to handle thousands of lines instantly without any noticeable lag.
- Is my data sent to a server?
- No. Like all Coders Kit tools, the processing happens entirely within your browser for maximum privacy and security.
- Does it remove duplicates based on case?
- By default, the tool performs an exact match (case-sensitive). This means 'Apple' and 'apple' would both be kept as they are considered different.
