When using ISREF, the most common questions are about result meanings, input format, and batch use; this FAQ includes 3 common questions.
FAQ
What do TRUE and FALSE mean in ISREF results?
- Enter
=ISREF(argument)in a cell. - If the result is TRUE, the argument is a reference.
- If the result is FALSE, the argument is not a valid reference, or the current expression does not form a reference.
What should I do if the ISREF result is not what I expected?
- Check whether the argument points to the correct cell, range, or defined name.
- Check whether the parentheses, separators, and formula format are correct.
- Split a complex expression into smaller parts, test each part separately, and then rebuild the formula.
How can I use ISREF in multiple cells at once?
- Enter the ISREF formula in the first cell and confirm the result.
- Select that cell and drag the fill handle across the target range, or copy and paste it.
- Check whether relative and absolute references behave as expected before applying it to a full row or column.
