Convert this acting script into clean JSON for copy-pasting into a rehearsal app.

Return ONLY valid JSON. No markdown. No explanation.

Format:
[
  {
    "speaker": "CHARACTER NAME",
    "text": "Dialogue line only"
  }
]

Rules:
- Keep dialogue in script order.
- Use uppercase character names.
- Exclude stage directions unless they are inside spoken dialogue.
- If a character has multiple paragraph lines before another character speaks, merge them into one text value.
- Do not summarize or rewrite dialogue.
- Generate JSON in a .txt file, dont output in chat,  for all the characters and lines in the script, even if some lines are repeated or have the same speaker.return the complete JSON in .text file (all characters, all lines, in order)
- Preserve punctuation as closely as possible.
- Preserve the original words exactly, but fix obvious broken spacing from PDFs or scans.
- Character names must not be split by spaces. Example: "M I C H A E L" becomes "MICHAEL"; "ANN ETTE" becomes "ANNETTE".
- Dialogue words must not be split into letters. Example: "a r e y o u r e a d y" becomes "are you ready".
- Do not add new dialogue, remove dialogue, modernize wording, or paraphrase.
- The final answer must be ready for a non-technical user to copy and paste directly.
