Preguntas frecuentes

Is my data safe?
Yes. All processing happens entirely in your browser. Your data never leaves your device and is never uploaded to any server.
Is sorting case-sensitive?
By default sorting is case-insensitive, so 'Apple' and 'apple' sort to the same position. You can toggle case-sensitive mode if you need 'A' to come before 'a'.
How does numeric sorting work?
Numeric sort treats each line as a number and sorts by value rather than alphabetically. This ensures '10' comes after '9' rather than between '1' and '2'.
Does deduplication preserve the original order of first occurrences?
Yes. When deduplication is enabled, the first occurrence of each unique line is kept and subsequent duplicates are removed. Sort order is then applied after deduplication.
Can I sort by a specific column in CSV data?
The line sorter treats each line as a unit. For column-based CSV sorting, use the JSON-CSV Converter to work with the data as structured fields.

¿Qué es Sort & Deduplicate?

Sort lines of text alphabetically, numerically, or by line length, and remove duplicate lines with one click. Ideal for cleaning up keyword lists, sorting log output, deduplicating email lists, and organizing CSV rows. Supports ascending and descending order, case-sensitive and case-insensitive sorting, and optional trimming of leading and trailing whitespace. All processing happens instantly in your browser — your text never leaves your device. No sign-up or installation required.

¿Por qué usar Sort & Deduplicate?

  • One-click deduplication — remove repeated lines instantly without manually scanning a long list.
  • Multiple sort modes — alphabetical, reverse alphabetical, numeric, and by line length.
  • Case-insensitive option treats 'Apple' and 'apple' as the same word when deduplicating or sorting.
  • Handles lists of any size — sort hundreds or thousands of lines in milliseconds.
  • Completely private — your text stays in your browser. Paste email lists or internal data safely.

Casos de uso de Sort & Deduplicate

Keyword list management

Sort and deduplicate SEO keyword lists before importing them into Google Ads, SEMrush, or other tools that charge by unique keyword.

Consejos y buenas prácticas

  • 💡Trim whitespace before sorting to avoid treating ' apple' and 'apple' as different lines due to leading spaces.
  • 💡For numeric sorting, ensure each line contains only a number — lines with mixed text and numbers will sort alphabetically.
  • 💡If deduplication removes lines you wanted to keep, check case sensitivity — 'Apple' and 'APPLE' may be treated as the same line.
  • 💡Reverse sort is useful for finding the longest or most recently added items at the top of a list.

Cómo se compara

Text editors like VS Code support sorting selected lines via a built-in command (Sort Lines Ascending/Descending), but do not offer deduplication or numeric sort without an extension. Spreadsheet tools like Excel can sort and deduplicate but require importing the data as a structured table first. This tool is faster for plain-text lists — just paste, configure, and copy the result.
