Hey all,
I hope this helps you save some dev time, as it was a rather slippery one to pin down...
This custom function will take all hyperlinks in a Google Sheets cell, and return them as text formatted based on the second parameter as either [JSON|HTML|NAMES_ONLY|URLS_ONLY].
Parameters:
cellRef : You must provide an A1 style cell reference to a cell.
Hint: To do this within a cell without hard-coding
a string reference, you can use the CELL function.
eg: "=linksToTEXT(CELL("address",C3))"
style : Defines the formatting of the output string.
Valid arguments are : [JSON|HTML|NAMES_ONLY|URLS_ONLY].
