Sort text A-Z or Z-A, optional numeric sort, sort by delimiter column index, copy sorted output - private browser-only text processing. ### Sort options Direction Numeric sort Column delimiter (optional) _, or \\\\t_ Column index (0-based) _0_ ### Input _One line per row…_ ### Output (sorted) _Sorted lines appear here…_ Copy result Clear ## What is an online sort lines tool? Sort lines alphabetically is one of those tiny utilities you reach for ten times a week: alphabetize guest names, order version numbers for a changelog, rank CSV rows by a price column pasted from a spreadsheet, or tidy bullet lists before sending meeting notes. ToolComb’s sort lines tool runs in the browser - paste input, pick A–Z or Z–A, optionally treat lines as numbers, optionally sort by a delimiter-separated column, copy output. No Excel, no terminal sort command, no upload. Alphabetic sort uses locale-aware localeCompare so accented characters and most Unicode letters order predictably for your browser locale. Numeric sort parses leading floats so 2 sorts before 10, fixing the classic lexicographic bug where string sort puts ten before two. Enable numeric when lines are integers, prices, or semver-ish tokens that start with digits. Column sort splits each line on a delimiter you provide - comma, tab, pipe - and compares the field at a zero-based index while moving entire lines together. That mirrors ORDER BY column_two in SQL when each row is already serialized as TSV on one line. Missing columns behave as empty keys and float to the top in ascending sorts. Stable sorting in modern JavaScript preserves relative order among equal keys, which matters when secondary ordering was intentional in the source export. The tool does not dedupe; run remove duplicate lines afterward if sorted adjacency reveals duplicates you want gone. Output preserves original line content including trailing spaces on each line; only order changes. Blank lines sort like any other line - often early in ascending text sorts - so strip them first if you want compact lists. Privacy stays local. Sorted guest lists, revenue figures, and internal project codenames never hit ToolComb servers. Copy sorted output into tickets, GitHub comments, or Google Sheets. Combine with find and replace when prefixes must be normalized before sorting (001-item vs item-001). Combine with word counter when you need length stats after reordering documentation sections. Conference organizers alphabetize speaker bios pasted one per line before building printed programs. Wedding planners sort guest names for seating charts. Neither workflow needs Excel if the list arrives as email plain text. DevOps engineers sort semantic version strings lexically when numeric mode is off but switch numeric on for build numbers extracted from CI logs - one line per build artifact. Teachers sorting student rosters by last name sometimes use column sort on comma-separated Last, First rows with delimiter comma and index zero, avoiding manual column splitting. When delimiter is tab, paste from Excel often just works: column index selects which field drives order while the row moves intact - handy for inventory sheets exported as TSV. Reverse alphabetical order helps find bottom-of-alphabet entries quickly when reviewing long allowlists. Sorting does not remove duplicates; after sorting, visually adjacent duplicates stand out and you can hop to remove duplicate lines for a unique pass. Locale-aware ordering means Turkish dotted/dotless I and German eszett follow browser rules - document locale if order must match a server sort exactly. Competitive programming coaches sort sample input lines before explaining binary search solutions - numeric ascending on integer lines matches judge expectations. Library catalogers sort call-number lines pasted from legacy exports when the ILS report arrives unsorted. Plant nursery inventory lists sort by Latin species column using comma delimiter and column index 0 while common names stay attached on each row. Music playlist curators sort artist lines for festival posters when submissions arrive as one-name-per-line email text. Compliance officers sort policy ID lines before diffing against last year’s register to spot missing identifiers quickly at list tails. Auction catalogs sort lot number lines numerically when lot IDs are plain integers without alphanumeric suffixes. Archivists sort box barcode lines before packing lists ship to offsite storage vendors. Bug triage lists sort by severity column when pasted from CSV exports where severity is the second tab-separated field. ## How to sort lines of text online Alphabetize or numeric-sort a list in under a minute with these steps. 1. **Paste one item per line** Each sortable record occupies its own line. For column sort, keep delimiter-separated fields on single lines. 2. **Choose A–Z or Z–A** Ascending is default alphabetical order; descending reverses it. 3. **Toggle numeric sort when needed** Enable for numbers so 100 follows 99 instead of appearing before 20 in text order. 4. **Configure column sort (optional)** Enter delimiter and column index 0 for first field. Leave delimiter empty to sort by entire line. 5. **Review output and copy** Output updates live. Copy result for spreadsheets or scripts. Clear resets both panes. 6. **Dedupe after sorting** If sorted adjacency reveals duplicate lines, paste output into remove duplicate lines for a unique list while preserving alphabetical order among survivors. ## Before / after: sorting TSV inventory by quantity ### Before A warehouse paste lists sku\tname\tqty rows out of order: qty column reads 45, 9, 120, 12. Text sort would place 120 before 9 incorrectly if compared as strings without numeric mode. ### After Delimiter tab, column index 2, numeric ascending yields 9, 12, 45, 120 while keeping sku and name attached to each row. Simple name lists use whole-line A–Z with numeric off - fastest path for event seating charts. When dates appear as DD/MM/YYYY in one column, lexical sort is not chronological - normalize to ISO in find-and-replace first, then column-sort on the ISO field. ## Practical uses for sorting lines ### 1. Name and email lists Alphabetize attendees before mail merge. ### 2. Version lists Numeric sort for build numbers when semver strings start with digits. ### 3. CSV/TSV paste cleanup Column sort by price or date field without opening Excel. ### 4. Log level ordering Sort ERROR/WARN/INFO groups when each line is one event. ### 5. Glossary and index terms A–Z order for documentation appendices. ### 6. Hashtag campaigns Alphabetize tags for consistent social posts. ### 7. Test case lists Order scenarios alphabetically for QA scripts. ### 8. Path lists Sort file paths for readable directory dumps. ### 9. Priority queues as text Numeric ascending on priority column lines pasted from Jira CSV exports before manual triage. ### 10. Language codes Alphabetical ISO 639 lines for i18n config files where order affects dropdown display only, not logic. ### 11. ZIP and postal codes Lexical sort on zero-padded codes; disable numeric if leading zeros must string-sort as text. ### 12. Competitor SKU monitors Column sort on price field from scraped TSV pasted one product per line for quick min-max scanning. ## Sort lines options compared Spreadsheets, sort CLI, and this page all reorder rows. Pick based on where the data already lives. | Option | Column sort | Privacy | Best for | | --- | --- | --- | --- | | ToolComb sort lines | Delimiter + index | Browser-only | Paste lists | | Excel sort | Full grid | Local workbook | Multi-column tables | | sort command | Whole line keys | Terminal | Files on disk | | Python sorted() | Custom key | Local script | Automation | Use Excel when the table is already structured. Paste here for chat snippets and readonly exports. Unix sort -n handles files but not Slack pastes. JavaScript localeCompare numeric option mirrors part of this tool’s numeric mode - test here when you cannot run node -e in production. Spreadsheet sort mutates workbooks; ToolComb leaves your source file untouched because input never leaves the paste box until you copy output elsewhere. ## Limits and tips - Delimiter split is literal, not CSV-aware - quoted commas may split wrong. - Numeric sort uses parseFloat; non-numeric keys fall back to localeCompare. - Column index is zero-based; out-of-range indexes compare as empty. - Locale affects alphabetic order; different browsers may differ slightly. - Very large lists may feel slow on mobile. - Does not dedupe or trim unless you preprocess. - Reverse sort inverts comparator; stable ties keep input order. - Does not read files - paste only. - Multi-character delimiters are supported literally - regex split is not used. - Scientific notation lines parse as floats in numeric mode; very large integers may lose precision. - Descending numeric sort reverses float comparison; NaN keys compare inconsistently - clean data first. - Sorting empty input yields empty output without error. - Mixed-language lines sort by chosen column bytes, not translated glossaries. ## Privacy: local sorting Lines are sorted in memory in your browser; nothing is uploaded. Clear sensitive sorted output from shared clipboards after copy. Column sort keys are derived locally from delimiter splits; no column metadata leaves the tab. Sorted guest or employee lists stay on device until you explicitly copy them elsewhere. Numeric sort parses values in-browser without sending numbers to analytics endpoints. Sorting large lists may use more RAM temporarily, but RAM is not replicated to ToolComb servers. Use corporate-managed browsers with the same expectation as any local text editor. After sort, diff against input with the diff checker locally if you need audit evidence without cloud compare tools. Sorted salary or revenue lines in paste boxes are not logged server-side - treat copy actions like any local editor. Column delimiter characters inside quoted CSV fields may split incorrectly; preprocess quoted CSV in a spreadsheet if needed. Educational labs can demonstrate stable sort behavior without installing Python on student Chromebooks. HR teams sorting employee ID lines for badge printing keep numeric mode on when IDs are numeric-only strings. No third-party font or script loaders receive your sorted list content - sorting is pure in-page logic. ## Frequently Asked Questions ### How does numeric sort differ from alphabetic? Numeric sort compares parsed floating-point values so 2 comes before 10. Alphabetic sort uses localeCompare, so 10 can appear before 2. Mixed lines where some keys parse as numbers and others do not fall back to string comparison for non-numeric keys - clean non-numeric rows or split lists if that hybrid behavior surprises you. ### What is column sort? Each line splits on your delimiter; the chosen column index becomes the sort key while the full line moves with it. ### Which column index is first? Zero-based: 0 is the first column, 1 is the second, matching programmer conventions. ### Are blank lines preserved? Empty lines participate in sorting like any other line unless you remove them first with another tool. ### Is sorting stable? JavaScript sort is stable in modern engines; equal keys keep their relative order from the input. ### Is my list uploaded? No. Sorting happens locally in the browser. ### Can I sort tab-separated data? Yes. Set delimiter to tab or paste TSV and choose the column to sort by. Copy from Excel often inserts literal tab characters between cells when you paste into plain text - column index then selects qty, price, or date fields without re-exporting CSV from the spreadsheet program. ### Does case matter? Default localeCompare follows Unicode case rules for your browser locale. ### What if a row lacks the column? Missing columns sort as empty strings for that key. Rows with fewer delimiter-separated fields than your column index therefore cluster at the top in ascending text sorts. Pad short rows with find-and-replace or fix source exports if empty keys should not dominate the head of the list. ### Is the sort lines tool free? Yes. Unlimited local sorts without registration, no account wall, and no restriction on how many lines you reorder in a single session. ### How do I sort by the second column in CSV? Paste rows one per line, set delimiter to comma (or tab for TSV), set column index to 1 for the second field (zero-based indexing). Enable numeric sort if that column contains numbers. The full row moves with the sort key so you can copy sorted CSV-like lines back into a sheet. ### Will semver versions sort correctly? Pure semver (1.2.10 vs 1.2.9) is not fully semver-aware - numeric mode helps when each line is a single number, but dotted version strings sort lexically by localeCompare. For strict semver ordering, preprocess or use dedicated version tools; this page suits simple build integers or alphabetized tag names. ## Related text tools - [Remove Duplicate Lines](https://www.toolcomb.com/remove-duplicate-lines) - Unique lists after sorting. - [Find and Replace](https://www.toolcomb.com/find-and-replace) - Normalize fields before column sort. - [Word Counter](https://www.toolcomb.com/word-counter) - Count lines via paragraph metrics on prose. - [Case Converter](https://www.toolcomb.com/case-converter) - Normalize casing before alphabetical sort. ## Related Tools Discover more free tools that might help with your next task.
