Final answer:
The AutoFit feature automatically adjusts the column width to fit the widest data entry in a spreadsheet application such as Microsoft Excel.
Step-by-step explanation:
The feature that can change the column width of the data to match the widest data entered in that field is known as AutoFit. This function is particularly useful in spreadsheet applications like Microsoft Excel. It automatically adjusts the width of a column or the height of a row to accommodate the size of the data entered. To use AutoFit, you simply double-click the boundary line of the column header or select the column and then choose 'AutoFit Column Width' from the format options.
