Frequently Asked Questions

Is my text data safe?
Yes, absolutely. All processing happens entirely in your browser using JavaScript. Your text is never uploaded to any server.
What is natural sorting?
Natural sorting handles numbers within text intelligently. For example, it sorts "file1, file2, file10" correctly instead of "file1, file10, file2" (which is what alphabetical sorting would produce).
Can I sort CSV files?
Yes! Enable column mode and specify which column to sort by. You can use comma, tab, semicolon, or custom delimiters. The header row can be kept fixed.
How does the regex filter work?
The regex filter lets you include or exclude lines matching a pattern before sorting. For example, use '^#' to match comment lines, or '\d+' to match lines containing numbers.
What is block/paragraph sorting?
Block sorting treats groups of lines separated by blank lines as single units. Useful for sorting multi-line entries like addresses, code blocks, or paragraphs while keeping them intact.
What export formats are available?
You can export as plain text, JSON array, numbered list (1. 2. 3.), Markdown list (- bullets), or HTML unordered list. This makes it easy to use sorted data in any application.
Are there any limits on text size?
There are no artificial limits. You can process as much text as your browser can handle. For very large files, performance depends on your device.
