Sort Lines
Sort multiline text alphabetically or numerically.
Sort Lines orders one-item-per-line text by A to Z, Z to A, numeric value, or line length. Optional settings let you compare case-insensitively and remove duplicate lines first.
Tool area
How to use
- Paste multiline text into the input area.
- Choose A to Z, Z to A, numeric, or length sorting.
- Optionally ignore case and remove duplicate lines.
- Copy the sorted result.
Use cases
- Alphabetize keywords, tags, or to-do items.
- Sort numbers, scores, quantities, or prices.
- Find unusually long headings, labels, or snippets by length.

How to verify a Sort Lines result before relying on it
This is a reproducible review method, not another list of button instructions. Start with a small baseline whose answer you can predict, test one boundary condition, and only then use real material. Line endings, Unicode, punctuation, encoding, and destination-platform rules can change how the same text is counted, cleaned, or formatted.
Establish a predictable baseline
Use “Alphabetize keywords, tags, or to-do items.” as the first test case. Begin with “Paste multiline text into the input area.” and write down the expected result before clicking anything. If the output differs, check units, formatting, whitespace, file page count, and selected options before assuming either the tool or source data is correct.
Probe an edge or failure case
For a second run, adapt “Sort numbers, scores, quantities, or prices.” and deliberately include one empty value, extreme value, duplicate, unusual character, large file, or unsupported format. The relevant boundary is: Alphabetical results can vary with browser locale and case-sensitivity options. This tells you when the page should be used as a draft aid rather than the final authority.
Cross-check before acceptance
The page is designed to “Sort multiline text alphabetically or numerically..” Write down the output you expect before running it; this makes format and setting errors easier to spot. If the result will be shared, imported elsewhere, used to replace an original file, or affect money or grades, also complete the final action “Copy the sorted result..” Keep the input assumptions and untouched source so another person can reproduce the decision later.
Acceptance checklist
- Input: confirm that the source, units, timezone, encoding, or file format matches the fields on Sort Lines.
- Process: run one small case you can judge independently, followed by one likely edge case.
- Output: compare counts, pages, dimensions, totals, timing, or format, and reopen any downloaded file.
- Decision: retain the source and verify important output against official rules, the destination system, or a second method.
Who is it for
- Users organizing lists, codes, and small text datasets
- QA teams comparing alphabetical and numeric ordering
- Students and administrators cleaning pasted text
Real examples
Sort a list containing numbers
Decide whether values such as `2` and `10` should use numeric or lexical order, then choose the matching mode. Inspect the first and last results, especially leading zeros, negative values, decimals, and mixed text.
Create a stable list for comparison
Normalize case and surrounding whitespace before sorting, then remove duplicates if needed. This makes manual comparison easier but does not understand names, natural-language collation, or every locale-specific ordering convention.
Good to know
- Alphabetical results can vary with browser locale and case-sensitivity options.
- Sorting changes source order, so keep an untouched copy of important data.
- The tool works line by line and does not parse CSV quoting, columns, or multiline cells.
FAQ
- How does numeric sort handle non-numeric lines?
- The tool reads a number from the start of each line. Lines without a number are placed after numeric lines and sorted as text.
- Which duplicate is kept?
- The first matching line is kept before sorting runs.
- Are blank lines preserved?
- Blank lines are ignored so the output is easier to copy into lists or spreadsheets.
