Reverse original physical line items while retaining spaces and blanks, with explicit LF newline normalization.

Built by Saurabh Kumar

Quick Answer

Reverse original physical line items while retaining spaces and blanks, with explicit LF newline normalization. Input is limited to 1,000,000 UTF-16 units and 20,000 physical items; review meaningful whitespace and record structure before copying.

Reverse the order of physical line items without reversing the characters inside each item. Blank rows, surrounding spaces and labels remain. This is the same transformation as Reverse Original Input in Sort Lines, offered here as a direct single-task workflow.

Reversing Line Order, Not Characters

Reverse the order of physical line items without reversing the characters inside each item. Blank rows, surrounding spaces and labels remain. This is the same transformation as Reverse Original Input in Sort Lines, offered here as a direct single-task workflow. Examples: reversing independent one-line labels, comparing an original order with its exact reversal, and seeing where boundary empty items move.

Reversing a list in one paste

Paste one independent item per line and inspect the reversed result. A trailing separator is a final empty item and will move to the beginning. Copy the output or select it manually if clipboard access fails.

Line endings and blank items

Input recognizes CRLF, LF and CR separators and output uses LF. Empty input has zero items; whitespace-only input is retained rather than silently discarded. The full item array is reversed without trimming, renumbering or changing character order. Reversing twice restores item text and order with normalized LF endings, not original mixed newline bytes.

Reference: ECMAScript array reversal. Line endings may already be normalized by the textarea or clipboard.

What reversing does not do

One physical line must represent one independent item. This is not timestamp sorting and does not infer chronological order. Numbered labels stay as written; reversing a numbered list will not renumber it. Multiline CSV fields, logs or code records can be broken by reversing their individual physical lines.

Flipping works on at most 1,000,000 UTF-16 units and 20,000 items. Larger input or a missing required browser API clears the result and shows an error, and the limits are not a speed guarantee. Empty output disables Copy. Keep the original if whitespace or record order carries meaning.

Choose Sort Lines for English collation, numeric text comparison or length order, Merge Lines to join items after reviewing their order, and Text Reverse for character reversal. Retain the original file when its exact newline encoding matters.
