Use Reverse Words as a separate planning aid for Swap Plus in Words With Friends: it reverses non-whitespace token order while preserving every original space, tab, and line-break run in the pasted text. Swap Plus and text reversal solve different jobs. The game-side action concerns exchanging tiles, while Reverse Words operates only on pasted text in a browser field; it cannot inspect a board, press a game control, or choose tiles. That distinction matters because exchanging tiles is not the same as turning a phrase backward. If your goal is to rehearse a phrase, inspect how candidates read in reverse token order, or check the exact separators around letter groups, paste the material into the linked Reverse Words tool and follow the three actions below. Treat the result as a planning reference, then return to Words With Friends to make the actual game choice yourself. The transformation is deterministic: “one two three” becomes “three two one,” while every token keeps its internal characters. It does not repair spelling, move punctuation according to grammar, infer a legal game move, or preserve meaning after the order changes. Processing stays inside the browser, so the text is not uploaded.
Separate the tile exchange from the text result
The keyword “Swap Plus in Words With Friends” can point to two different tasks. In the game, it refers to exchanging selected tiles. In a text exercise, you may instead want the words in a phrase or list to appear in the opposite order. Reverse Words handles only the second task. It accepts pasted text, not board state, rack tiles, or a proposed game move.
If you want to reverse token order in pasted text, use Reverse Words as a separate browser tool. If you are planning how text reads backward, run that text through Reverse Words separately. Its output can help you compare token order, but it does not confirm that a candidate is valid English or legal in the game.
Run the text check for a Swap Plus plan
Use the browser tool beside the game rather than as an extension of it. Prepare the exact phrase, sentence, list, or multiline block you want to inspect, including the separators you want tested.
- Paste the source text. Paste text whose non-whitespace token order should be reversed. A letter group separated by spaces may become several tokens, while a joined sequence without whitespace remains one token. Keep the original spacing, tabs, and line breaks in the pasted value.
- Run the transformation. Select Reverse word order. The tool reverses the collected non-whitespace tokens, reports how many were reversed, and shows the exact output. Letters inside each token remain in their original order.
- Inspect the result before returning to the game. Verify the reversed tokens and confirm that original spaces, tabs, and line breaks stayed in place. Also check that attached punctuation and symbols still belong to the same tokens. The resulting text is a reference for your planning, not an automatic action on the game board.
If you edit the input after running the tool, the previous result clears. Run the operation again so that an old reversal cannot be mistaken for the output of the current text.
Identify the exact tokens being reversed
In Reverse Words, a word is any maximal sequence of non-whitespace characters. This definition is mechanical rather than linguistic. Letters, numbers, symbols, emoji, and punctuation are included when they are connected without whitespace. The tool reverses the order of those complete tokens; it does not reverse their internal spelling.
For example, “hello, brave world!” contains three tokens: “hello,”, “brave”, and “world!”. The result is “world! brave hello,”. The comma stays attached to “hello,” and the exclamation point stays attached to “world!”. The tool has not rewritten the punctuation to make the reversed phrase grammatical.
A joined emoji sequence without whitespace also forms one token, and combining marks remain attached to their surrounding token. Scripts that do not normally separate words with spaces can therefore produce a whole line or phrase as one token. The tool does not apply Chinese, Japanese, Thai, or other language-specific segmentation. If you need to mirror the characters within tokens instead, use the separate Text Reverser tool.
The operation matches alternating runs of whitespace and non-whitespace content, collects only the non-whitespace runs, reverses that collection, and substitutes the tokens back into the unchanged whitespace pattern. MDN’s references on regular-expression character classes and Array.prototype.reverse() provide useful background on those JavaScript building blocks. The result is still a token-order transformation, not a full character reversal.
Keep every whitespace run in its original slot
Whitespace is preserved by position rather than by moving with a word. Every whitespace run stays unchanged in its original token slot: one space remains one space, two spaces remain two spaces, and tabs remain tabs. CRLF, CR, and LF line endings also remain exactly where they appeared in the browser string. The tool never changes or relocates those boundaries.
Suppose the input contains “one”, followed by two spaces, then “two”, a line break, and “three”. The output contains “three”, the same two spaces, “two”, the same line break, and “one”. The token contents have exchanged places, but the supplied whitespace structure has not.
Fixed whitespace positions can make the visual result look unusual when the tokens have very different lengths. A short token moving into a long final slot does not cause automatic padding. Normal browser wrapping may also look different on screen. That visual wrap is not an inserted newline; the underlying characters remain the ones supplied in the input.
Check edge cases and the input ceiling
The tool validates both content and input length before producing a reversal.
| Input condition | Result |
|---|---|
| Empty or whitespace-only input | Rejected because it contains no non-whitespace token to reverse. |
| One non-whitespace token | Returned unchanged as a deterministic no-op, with a reported count of one. |
| Exactly 1,000,000 UTF-16 code units and at least one token | Accepted for processing. |
| One UTF-16 code unit beyond the limit | Produces a visible error and no partial result. |
| Input edited after a previous result | The previous result clears until the current input is processed again. |
The exact ceiling is measured in UTF-16 code units, so it should not be treated as a count of visible letters or glyphs. If the input is over the limit, reduce it before running the tool rather than expecting a partial reversal.
Review meaning before using the output
Reverse Words changes structure, not language. It does not act as a translator, sentence-level rewriter, grammar corrector, bidirectional-text sanitizer, or right-to-left layout converter. Moving tokens can make a sentence nonsensical even when every token and separator was processed correctly. Read the output as a deterministic transformation rather than as improved writing.
Mixed left-to-right and right-to-left scripts may also need a dedicated bidirectional-aware editor for visual review. Before publishing the result or inserting it into code, markup, commands, or structured data, confirm that changing token order will not alter the intended behavior. For a Words With Friends plan, use the reversed text only as a rehearsal aid, then check the actual tiles and game state yourself.
