Text Deduplicate & Sort Tool: Splits on newlines, removes duplicate occurrences using Set, and performs ascending alphabetical sort.
About this text deduplicate & sort tool
Text Deduplicate & Sort Tool — browser-based utility.
How this tool works
Implements client-side Text Deduplicate & Sort Tool operations. Splits on newlines, removes duplicate occurrences using Set, and performs ascending alphabetical sort specifically designed for a data analyst cleans an email list by removing duplicate addresses and sorting alphabetically.
- Line Stream Ingestion & Normalization: Splits input text on universal newline boundaries (CRLF, LF, CR) into indexed line arrays.
- Hashing & Set Intersection: Indexes unique lines in HashSets for rapid set comparison and deduplication.
- Sequential Filtering & Collation: Applies trimming, case-folding, sorting (ASCII or natural alphabetical), or prefix/suffix concatenation.
- Output Reconstruction: Joins result lines with user-selected line separators, providing item counts and reduction percentages.
Worked example
Scenario: Trim, deduplicate, and sort three text lines.
Sample input:
Processing: Trim, remove blanks, retain first values, then locale-sort.
Illustrative output:
Limits and verification
Handles multi-megabyte text payloads up to browser heap limits (~50-100 MB). Normalizes varied Unicode characters before comparison if case-insensitive mode is active. Preserves empty lines when configured.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

Frequently asked questions
How does Text Deduplicate Sort treat lines?+
It trims every line, removes blanks, keeps the first exact trimmed occurrence through Set, and sorts the remaining lines with localeCompare numeric true and base sensitivity.
What result does sort mode produce for a repeated line?+
For `Beta`, `alpha`, `Beta`, the tool keeps the first trimmed occurrences and returns `alpha` then `Beta`. The second field reverses that final order only when its trimmed, lowercased value is `desc`.
Which text semantics are not preserved?+
Leading and trailing whitespace, blank-line placement, duplicate occurrence count, and original order are discarded. The comparison behavior comes from the current browser locale; it is not a stable byte sort.
Does sorting send text or modify files?+
It sorts the text entered in this browser and displays the result. It does not inspect, upload, rewrite, or rename files.
