Common MID questions usually involve argument errors, unexpected results, and batch filling; this FAQ covers 3 frequent questions and practical fixes.
FAQ
What should I do if MID returns a #VALUE! error?
- Check whether the starting position and extraction length are valid numbers.
- Make sure the formula does not use Chinese commas, extra spaces, or incorrect cell references.
- If the source data contains extra spaces or hidden characters, try cleaning it with functions such as TRIM or CLEAN before testing again.
Why does the MID result not match what I expected?
- Confirm that character counting starts from 1.
- Check whether the extraction length covers the exact range you want.
- If the formula refers to another cell, make sure the referenced content and position have not shifted.
How can I use MID in multiple cells at once?
- Enter the correct MID formula in the first target cell.
- Move the pointer to the fill handle at the lower-right corner of the cell and drag downward.
- After filling, review the references and use $ if you need to lock rows or columns.
