hyperlink property
A hyperlink this cell points to, if any.
If the cell contains multiple hyperlinks, this field will be empty. This
field is read-only. To set it, use a =HYPERLINK
formula in the
userEnteredValue.formulaValue field. A cell-level link can also be set
from the userEnteredFormat.textFormat field. Alternatively, set a
hyperlink in the textFormatRun.format.link field that spans the entire
cell.
