How to use Sort Lines

What the tool does, how to run it, and what to expect from the result.

How to sort lines of text

To sort lines, paste your list into the box, choose ascending or descending, and pick whether the comparison should respect letter case. The reordered result appears instantly in your browser, ready to copy back into a spreadsheet, document, or code file.

Case-insensitive sorting groups uppercase and lowercase together so Apple and apple sit next to each other, while case-sensitive sorting keeps the strict character order. Choose whichever matches how you want the list to read.

  • Paste your lines of text
  • Choose ascending or descending
  • Toggle case-sensitive comparison
  • Copy the sorted result

Why a focused sorter is enough

Most line-sorting jobs do not need a heavy text suite; they need a predictable alphabetical sort with a couple of practical options. Sort Lines keeps the workflow fast by doing exactly that and nothing more.

It works well for cleaning up keyword lists, deduplicating prep, alphabetizing names, ordering URLs, or organizing any plain-text list before pasting it somewhere else.

Tips

Getting a better result out of Sort Lines

Specific settings and thresholds, not general advice.

  • The sort is natural, not alphabetical. Numbers embedded in the lines are compared as numbers, so item2 comes before item10 rather than after it, which is the opposite of what a plain string sort does.
  • Case-insensitive is the default. In that mode accents are ignored too, so resume and résumé compare as equal and their relative order is left as it was found.
  • Turning on case-sensitive compare makes the collator distinguish both case and accents, which is what you want when sorting identifiers or anything where A and a are genuinely different values.
  • Descending is implemented as the ascending sort reversed, so blank lines that sort to the top in ascending order end up at the bottom in descending order.
  • Sorting does not deduplicate. Identical lines end up adjacent, which makes them easy to spot, but you still need Dedupe Lines to remove them.
Limits

What Sort Lines does not do

The honest boundary, so you do not lose time finding it yourself.

  • It sorts whole lines. There is no sort by column, by field or by a custom key.
  • There is no numeric-only mode, no length sort and no reverse-string sort.
  • It does not remove duplicates or blank lines.
  • The output is joined with LF, so CRLF input comes back with Unix line endings.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is Sort Lines free?

Yes. It is free and runs entirely in your browser, with no account or limits.

Does it upload my text?

No. Sorting happens locally in your browser, so your list never leaves your device.

Can I sort descending too?

Yes. Both ascending and descending order are supported.

Can I ignore letter case?

Yes. Case-insensitive comparison is available, so uppercase and lowercase entries sort together.

What kinds of lists can I sort?

Any line-based text works, including names, keywords, URLs, file lists, and other plain-text data.

Does it put 10 before 2?

No, and that is deliberate. The comparison uses a collator with numeric mode enabled, so digit sequences inside the lines are compared by value rather than character by character. file2 sorts before file10, and v1.9 sorts before v1.10. A plain string sort would get both of those wrong.

What does the case-sensitive checkbox actually change?

With it off, the comparison ignores both case and accents, so Apple, apple and Àpple all compare as equal and keep their existing relative order. With it on, the comparison distinguishes case and accents, which is what you want for identifiers, keys or anything where the exact characters matter.

Where do blank lines end up?

At the top in an ascending sort, because an empty string sorts before everything. In a descending sort they end up at the bottom, since descending is the ascending result reversed. If you do not want them at all, run Remove Empty Lines first.

Can I sort a CSV by one of its columns?

Not with this tool. It sorts whole lines as strings, so a CSV would be sorted by whatever happens to be in the first column, and any line whose first field ties would be ordered by the second, and so on. For real column sorting, use a spreadsheet.

Does sorting remove duplicates?

No. Duplicate lines all survive and end up next to each other, which makes them visible. If you want them gone, run Dedupe Lines, which keeps the first copy of each distinct line.

Is the text uploaded?

No. The sort happens in the page using the browser's own collator, so nothing is sent anywhere.
