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): 'Volym P5_P6_2023'!I2:I10 Expected answer sheet(s): Task: In my Excel sheet, I'm struggling to display multiple dates in a single cell in Column I using a date format rather than numerical values. Specifically, for cells containing more than two dates, such as in row 2 with three dates, my attempt with the TEXT function has been unfruitful. How can I apply a formula directly in Column I that will allow me to join these various dates with a delimiter and still maintain the date formatting, without having to resort to using a helper column? My current formula is : TEXTJOIN(",",TRUE,UNIQUE(IF(A2=ZORD!A:A,ZORD!C:C,""))). Dates should be in the format DD/MM/YYYY.
