Browser-basedWhat this tool does

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.

Representative tasks

What you can do with this tool

Clean keyword and URL lists

Trim accidental spaces, remove repeated campaign keywords or submitted URLs, and optionally sort the final list for a stable review or export.

Deduplicate IDs before an import

Produce a stable first-seen list of order, account, or ticket identifiers before validating it in the destination system.

Normalize copied logs and spreadsheet rows

Remove blank rows and line-edge whitespace from copied data, or sort repeated log labels into numeric-aware order before comparing them.

Boundaries

What to check before relying on the result

  • 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.

How to use

  1. 1

    Paste one record, keyword, identifier, or log entry per line.

  2. 2

    Choose Deduplicate, Sort lines, or Trim whitespace and set only the options shown for that operation.

  3. 3

    Review the counts and output order, then copy the result only after deciding whether case and whitespace differences should remain distinct.

Tips & Tricks
Choose the operation order deliberately

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.

Preserve first-seen priority

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.

Validate records separately

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.

FAQ

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.
