## Frequently asked questions

### Can I remove prefixes from only specific lines?

Yes, you can use the 'Target Lines' option to select all lines, only non-empty lines, or specific patterns like odd or even lines.

### Does this tool preserve my original indentation?

Yes, if you enable the 'Preserve Indentation' checkbox, the tool will keep your existing whitespace and remove the prefix only after the indentation.

### What happens if a line does not contain the specified prefix?

The tool will leave that line unchanged and proceed to process the remaining lines.

### Can I remove empty lines while stripping prefixes?

Yes, you can enable the 'Ignore Empty Lines' option to skip processing or effectively remove empty lines from your output.

### Is there a limit to the amount of text I can process?

The tool is designed to handle standard text blocks efficiently; for extremely large files, we recommend processing in smaller chunks.
