What the agent was asked to do

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): C1:C6066 Expected answer region(s): 'Data to Import'!C1:C6066 Expected answer sheet(s): Data to Import Task: I have an Excel VBA issue where I'm trying to remove the last three characters from each postcode in a column, and the number of rows can range from 1 to 500,000. My current code is erroneously changing every value in the column to FALSE instead of removing the characters. Here's the code I'm using: Sub RemoveChar() Dim ws As Worksheet Dim c As Range Set ws = Worksheets("Data to Import") For Each c In ws.Range("C2", ws.Range("c" & ws.Rows.Count).End(xlUp)) c.Value = ("C2") = Left(ws.Range("C2"), Len(ws.Range("C2")) - 3) Next c End Sub Can anyone explain what I'm doing wrong with this code?
