Frequently Asked Questions

Are my lists or text files uploaded to any servers?

No. All parsing, text cleaning, and processing mechanics execute locally via vanilla JavaScript. Your secure corporate lists or sensitive code strings never leave your local workspace frameworks.

Is there a file length limitation for this text tool?

There are no server limits imposed. Performance relies entirely on your local device hardware memory threshold and browser processing speeds for massive data arrays.
