Word Search Word Extraction

I have several word search puzzles and need a clean, accurate list of every “word-to-find” contained in each one. No grid graphics, coordinates, or highlights are necessary—just the complete vocabulary pulled straight from the puzzles and delivered as plain-text files.

The job is straightforward: scan or parse each puzzle, capture every target word exactly as it appears (preserving spelling and capitalization), and supply one .txt file per puzzle or a single consolidated text file if that is easier for you. Speed is appreciated as long as accuracy is maintained. If anything in a puzzle is ambiguous, flag it so I can double-check.
