Line Cleaner
Deduplicate, sort, or trim multiline text in one focused browser workspace.

浏览器内运行这个工具能做什么
Clean pasted text with three explicit line operations: remove exact duplicates while preserving first-seen order, sort lines with numeric-aware and case options, or trim line edges and optionally remove empty rows. Each operation reports task-specific counts before you copy the browser-local result.
Deduplicate keeps the first exact copy of each line and discards later copies without sorting. Sort uses numeric-aware comparison and can run descending or case-sensitive. Trim can remove leading and trailing whitespace, empty lines, or both.
Operation order still matters: if spaces are accidental, trim first and then deduplicate the trimmed output. If first-seen order carries priority, deduplicate before sorting or stop after deduplication.
这个工具可以完成什么
Trim accidental spaces, remove repeated campaign keywords or submitted URLs, and optionally sort the final list for a stable review or export.
Produce a stable first-seen list of order, account, or ticket identifiers before validating it in the destination system.
Remove blank rows and line-edge whitespace from copied data, or sort repeated log labels into numeric-aware order before comparing them.
依赖结果前需要检查什么
- Performance and maximum practical input size depend on browser memory, device speed, and the structure of the input.
- Review the generated result before replacing or publishing an original file.
如何使用
- 1
Paste one record, keyword, identifier, or log entry per line.
- 2
Choose Deduplicate, Sort lines, or Trim whitespace and set only the options shown for that operation.
- 3
Review the counts and output order, then copy the result only after deciding whether case and whitespace differences should remain distinct.

使用技巧
Trim first when indentation and trailing spaces are accidental, then paste that output back into Deduplicate. Apply case normalization separately if Foo and foo should become the same key.
Deduplicate does not sort, so the earliest occurrence keeps its position. Switch to Sort lines only when alphabetical or numeric-aware order is the actual requirement.
A clean or unique line is not necessarily a valid URL, ID, or email. These operations reshape plain text and do not validate the record format.
常见问题
Does deduplication keep order?
Yes. The first appearance of each exact line is preserved, and later matches are removed.
Is deduplication case-sensitive?
Yes. Whitespace is part of the exact line value too, so API and api or item and item followed by a space remain separate values.
Can sorting handle numbers and capitalization?
Yes. Sorting uses numeric-aware comparison, so 2-grid sorts before 10-grid. You can choose ascending or descending order and whether capitalization affects comparison.
Can I remove blank lines without trimming other text?
Yes. In Trim whitespace mode, disable Trim line edges and enable Remove empty lines. Lines containing only whitespace count as empty for removal.
Can I run all three operations at once?
No. One operation runs at a time so its effect and metrics stay clear. Copy the output back into the input before selecting the next operation.
