Spreadsheet Grammar Error Correction

I have a single spreadsheet containing a little under 1,000 rows of text-heavy data. I need every cell reviewed and any grammar errors corrected — punctuation, agreement, sentence structure, and similar issues. Please leave numbers, formulas, column widths, and other formatting exactly as they are; I am only interested in grammatical accuracy, not typographical or layout fixes. You’ll receive the file in Excel but you are welcome to use Google Sheets or any other editor, as long as the final deliverable comes back in the same .xlsx format with all original sheets intact. A simple change-log or cell-highlight for the edits would be helpful so I can spot-check the work quickly. Once I confirm that every row is clean and nothing else in the sheet was altered, the task is complete.
