Sort Lines Online — Alphabetical, Numeric & Length Sort Free
Sort any list of lines alphabetically, numerically, or by length — in ascending or descending order. Optionally remove duplicates, drop blank lines, and ignore case. Everything runs in your browser — no upload, no account, no logs.
How to use this tool
- Paste your lines of text into the input.
- Choose sort order (A-Z, Z-A, or by length).
- Copy the sorted output.
About Sort Lines
Sorting a list of lines sounds trivial until you actually need it. Spreadsheets force your data into a grid, command-line sort tools have a learning curve, and word processors do not sort plain text well. This tool takes any multiline text and reorders the lines according to the rules you pick, then shows the result with a line count so you can see what changed. It is built for the everyday job of putting a list in order, whether that list is names, numbers, file paths, or log entries.
Three sort criteria are available. Alphabetical orders lines by their text, the default and most common choice. Numeric reads the numeric value of each line and sorts by magnitude, with non-numeric lines pushed to the end so a mixed list does not break. By Length sorts according to how many characters each line contains, which is handy for finding the longest or shortest entries. Each criterion can run in ascending order (A to Z, small to large) or descending order (Z to A, large to small) via the Order dropdown.
Three checkboxes refine the result further. "Ignore case" makes alphabetical sorting case-insensitive so capitalization does not scatter related entries. "Remove duplicates" keeps only the first instance of each line, combining cleanup with sorting in a single step. "Drop blank lines" discards empty lines so the output is compact. You can mix these freely, for example sorting alphabetically while ignoring case and stripping blanks at the same time.
The output appears in a scrollable monospace panel and a Copy button places it on your clipboard. Writers use it to alphabetize glossaries, developers to order import statements or configuration keys, analysts to rank numeric lists, and anyone tidying a messy list. It runs entirely in your browser, so the lines you paste stay on your device.
Frequently Asked Questions
- What sort orders are supported?
- You can sort alphabetically, numerically, or by line length, and each can run ascending (A to Z, smallest first) or descending (Z to A, largest first) using the Order dropdown.
- How does numeric sorting handle non-numeric lines?
- Numeric sorting reads the number in each line and orders by value. Lines that do not contain a usable number are moved to the end rather than mixed into the numeric sequence.
- What does "By Length" sort by?
- It orders lines by their character count, so you can group the shortest or longest lines together. Choose ascending for shortest first or descending for longest first.
- Can I sort and remove duplicates at the same time?
- Yes. Enable the "Remove duplicates" checkbox and the tool keeps only the first instance of each line while it sorts, so you get an ordered, deduplicated list in one step.
- What does "Ignore case" affect?
- It makes alphabetical sorting case-insensitive, so lines like Apple and apple are grouped together instead of being separated because uppercase letters normally sort differently from lowercase ones.
- How do I remove empty lines?
- Turn on "Drop blank lines" and the tool discards empty lines from the output, leaving a compact, gap-free list.
- Does it tell me how many lines I have?
- Yes. The result shows a line count alongside the sorted output, which is a quick way to confirm how many entries remain after deduplication or dropping blanks.
- Is anything uploaded?
- No. Sorting runs entirely in your browser, so the text you paste is never sent to a server.
