The output is not what I expected.
Confirm the reverse, case-insensitive and numeric options. Sorting uses the runtime's default Intl.Collator locale, so tie order can vary between environments.
Sort Text Lines Tool
Reorder one item per line using alphabetic, numeric or reverse sorting controls.
What this tool does
Sort Text Lines treats every line as one sortable item. Numeric ordering places embedded numbers naturally—for example, file2 before file10—while duplicate lines remain unless you run a separate deduplication step. Sorting uses the runtime's default Intl.Collator locale, so tie order can vary between environments.
Paste one item per line, choose the sort rules and copy the reordered list.

How to use it
Paste one sortable item per line.
Choose case handling, numeric ordering and normal or reverse direction.
Review locale-specific order, then copy or deduplicate the sorted list.
Key features
- Locale-aware line comparison.
- Optional case-insensitive and numeric sorting.
- Normal or reverse direction.
Practical use cases
- Alphabetising names, labels or keywords.
- Putting filenames and numbered values into natural order.
- Normalising list order before a comparison or review.
Limitations and important notes
- Sorting uses the runtime's default Intl.Collator locale, so tie order can vary between environments.
- Duplicates are retained.
- Each full line is one item; use Word Sorter for individual words.
Troubleshooting
The page becomes slow with a large input or repeat count.
Reduce the input, split the operation into smaller batches and close other memory-heavy tabs. Keep an original copy before retrying.
The result changes after I paste it elsewhere.
Test the destination app, font and character encoding. Some apps normalize whitespace or render Unicode differently.
Frequently asked questions
How do I sort lines alphabetically?
Sort Text Lines treats every line as one sortable item. Numeric ordering places embedded numbers naturally—for example, file2 before file10—while duplicate lines remain unless you run a separate deduplication step.
Does it remove duplicates?
No. Use Remove Duplicate Lines before or after sorting.
What is numeric sorting?
It compares embedded digit sequences as numbers so values such as item2 can precede item10.
What are the limitations?
Sorting uses the runtime's default Intl.Collator locale, so tie order can vary between environments. Duplicates are retained. Each full line is one item; use Word Sorter for individual words.
