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): Expected answer region(s): C2:C16 Expected answer sheet(s): Task: Replace the data in Columns B:C where Monday is to be represented as day 1 and Sunday as day 7 in column B, and Column C is the actual day of the week corresponding to the Date in Column A. Despite setting Monday as day 1 in the calendar, Excel might be defaulting to Sunday as day 1 for some reason. Even trying to change the format to 'DDD' hasn't yielded the right results. The INDEX solution provided seems to solve the problem, but I'm still unsure about the reason why the WEEKDAY function isn't performing as expected. Do not change any formatting.
