SpreadJS provides an INDIRECT function similar to Microsoft Excel.
INDIRECT returns the reference specified by a text string. References are immediately evaluated to display their contents. Use INDIRECT when you want to change the reference to a cell within a formula without changing the formula itself.
INDIRECT supports a1-style reference, r1c1-style reference, named reference, or a reference to a cell as a text string. For invalid cell references, INDIRECT returns the #REF! error value.
