You are solving a spreadsheet benchmark task in a real workbook. Objective: Produce the correct final workbook state for the expected answer region. What matters: - Only the values in the expected answer region will be graded. - The workbook is the answer. Instructions: 1. Read the workbook and inspect the relevant data region first. 2. Infer the required result for the provided workbook instance. 3. Write the final value(s) directly into the expected answer region. 4. Do not rely on prose, formulas in your chat response, pseudocode, or VBA as the answer unless the benchmark explicitly requires those to be written into cells. 5. If the natural-language task asks for a general method, formula, or macro, convert that into the concrete result needed for this workbook instance. 6. Keep your final text response short and only summarize the workbook cells you changed. Relevant data region(s): A1:A19 Expected answer region(s): 'Sheet1'!A2:A19 Expected answer sheet(s): Sheet1 Task: I have an Excel spreadsheet with a column of dates where some cells include a time value that starts with 'T' and ends with 'Z' and these strings are 14 characters long. I'm seeking assistance to modify an existing macro to remove these time values, leaving just the date in each cell of column A. Outputs should adhere to m/dd/yyyy (see existing A2 format)
