About Lines Sorter
Lines Sorter rearranges text entries in alphabetical, numeric, or length order. You can process one item per line or choose comma-separated input. Sorting is useful for cleaning lists, but it changes the original order, so keep a copy if that order carries meaning.
Lines Sorter reorganizes a list using one of several comparison rules. It can sort items alphabetically, in reverse alphabetical order, numerically, or by text length. Because sorting changes order, use it only when the original sequence does not carry meaning, or keep a source copy before you run it.
How to use this tool
- 1Paste the entries and select whether they are separated by new lines or commas.
- 2Choose the sort order: A–Z, Z–A, numeric ascending or descending, or shortest to longest (and the reverse).
- 3Sort the text and inspect the result, especially mixed numbers, punctuation, and blank entries, before copying it elsewhere.
Main features explained
01A–Z and Z–A
Alphabetical modes use the browser's locale-aware Intl.Collator with numeric comparison and base sensitivity. This generally ignores case differences and handles embedded numbers more naturally than a basic character sort, though punctuation and locale rules still affect ordering.
02Numeric order
Numeric modes extract digits, periods, and minus signs from each item and compare the resulting number. This can sort numbered labels, but mixed text can produce surprising values, and items with no numbers do not have a useful numeric value.
03Shortest or longest first
Length modes compare JavaScript string length, then use the alphabetic collator to break ties. That count is based on string code units, so some emoji or combined characters may count differently from what a person sees as one symbol.
04Line or comma-separated input
Per Line trims each line and removes blank entries. CSV mode splits at commas and newlines, trims each item, then returns comma-and-space separated values. It does not keep blank rows or parse quoted CSV fields.
How it works
The selected mode compares each split entry and returns the entries in the requested order. Alphabetical sorting follows the implementation's string comparison, numeric modes compare numeric values, and length modes compare character counts. It does not infer custom priorities or preserve grouped categories.
A quick example
Sorting `pear`, `apple`, `plum` from A–Z gives `apple`, `pear`, `plum`. Sorting by length instead places the shortest text first, regardless of its alphabetic position.
Worked examples
Alphabetical order
Before
pear apple plum
After
apple pear plum
A–Z compares the full item text. The input order is replaced by the sorted order.
Numeric order for labels

The numeric mode extracts digits from each item. Keep labels consistent and check lines with more than one number.
When it is useful
Organize names, labels, IDs, or simple lists; prepare alphabetized terms; or quickly spot out-of-order entries in a pasted block.
Alphabetizing a short list
Sort names, labels, keywords, or titles into a scan-friendly order. Check accents and symbols if the list must follow a specific language or organization rule.
Putting numbered items in order
Numeric sorting can arrange values such as `Item 2` and `Item 10` using the number found in each string. If each line contains several numbers, the extractor may combine them, so validate the output against a known example.
Finding short or long entries
Length sorting can put shorter labels first or reveal unusually long values at the top. It is useful for reviewing IDs, title lengths, or menu labels before applying a separate character limit.
Preparing a simple comma list
Comma mode can organize a basic set of tags or values and return them as one comma-separated line. Do not use it to rearrange structured CSV with quoted commas or multiple columns.
Tips for a better result
- Keep the original list if its order represents time, rank, priority, or steps in a process.
- Choose Per Line for normal lists. Use CSV only for simple comma-separated values with no quoted commas.
- Try the chosen mode on a few sample rows before sorting a long list, especially for numeric order.
- Blank lines are removed, and returned items are trimmed. Do not rely on the sorter to preserve intentional empty entries or indentation.
- If ties must stay in a particular order, confirm that after sorting instead of assuming the original order is preserved.
Technical details and limits
Sorting is not semantic: it cannot understand that some numbers are version labels or that items belong in sections. Comma mode splits at commas, so quoted CSV fields with commas can be broken apart. Review before using the new order.
The result depends on the text and options you provide. Keep a copy of the original when formatting matters, and review the output before using it in a document, site, or application. This guide describes the tool's behavior; it does not replace proofreading or checking a platform's own requirements.
Frequently asked questions
Does sorting keep the original order for ties?
Items with equal sort keys may retain or change their order based on the underlying sort behavior; verify if tie order matters.
Can I sort a CSV file?
You can sort comma-separated text, but this is not a full CSV parser for quoted fields.
What does length sort count?
It compares the text length of each split entry, including any characters the input contains.
Does alphabetical sorting ignore uppercase and lowercase?
The collator uses base sensitivity, so case differences generally do not decide the order. Locale and punctuation can still affect results.
How does numeric sorting handle text?
It extracts digits, dots, and minus signs from each line and converts them to a number. It is best for consistently formatted values.
Can it sort a real CSV file?
It can split simple comma-separated input, but it is not a CSV parser. Quoted commas and column relationships are not protected.
Will it keep blank lines?
No. Empty entries are filtered out before sorting.
What does length mean for emoji?
The tool compares string length in JavaScript code units, which may not equal the number of visible symbols.
Can I sort names in a particular national alphabet?
The browser locale influences alphabetic comparison, but this tool has no separate language selector. Verify names if strict collation rules matter.
