Proofread Data Analysis Report Text

I have finished drafting a data analysis report and now need a fresh set of eyes to polish the language. Your task is straightforward: go through the entire document and correct spelling and grammar errors only. Please do not alter wording for style, tone, or clarity—I want the analysis itself left exactly as written.

The report already follows a consistent English spelling style, so keep that intact when you make corrections. I would like the final file returned with clear markup (Track Changes in Word or similar) so I can review every edit easily, alongside a clean copy ready for submission.
