Opening and applying the tool
The entry screen accepts one UTF-8 TXT, CSV, JSON, XML, HTML or HTM file and opens the editor. Imports are text content, not a PDF or Word conversion. Review the source and choose Add Prefix to Text Lines when ready. Editing or importing alone does not apply the transformation.
Review, save or continue
The result is editable before you copy or download it.
Using the finished text
Edit the result if needed, then copy it or download UTF-8 TXT. Continue to offers compatible next tools based on the current result and their limits. It carries the text into a fresh destination workspace without running the next operation automatically.
