I have the same issue reported. Unfortunately, the concat formula does not work.
The behavior of the import has changed for fields that contained a formula that produced an html link using text excel concat functions. The previous versions imported the interpreted contents, the new version 2 imports the actual formula.
Previous in the 1.x versions, a formula such as
=CONCAT("<a href=", CHAR(34), "[amazon_s3 bucket=orcasecure object=ReelNewsDigital/TRN", [@Year], "0", [@Iss], ".pdf]", CHAR(34), " target=", CHAR(34),"_blank", CHAR(34), " rel=", CHAR(34), "noreferrer noopener", CHAR(34), ">", [@Year], "-", [@Iss], "</a>")
would be imported with the interpreted contents, which in this case produces a simple html link:
<a href="[amazon_s3 bucket=orcasecure object=ReelNewsDigital/TRN202301.pdf]" target="_blank" rel="noreferrer noopener">2023-1</a>
The new TablesPress import for version 2 now imports the field as a formula instead of contents, and produces:
"=_xlfn.CONCAT(""<a href="", CHAR(34), ""[amazon_s3 bucket=orcasecure object=ReelNewsDigital/TRN"", Table1[[#This Row],[Year]], ""0"", Table1[[#This Row],[Iss]], "".pdf]"", CHAR(34), "" target="", CHAR(34),""_blank"", CHAR(34), "" rel="", CHAR(34), ""noreferrer noopener"", CHAR(34), "">"", Table1[[#This Row],[Year]], ""-"", Table1[[#This Row],[Iss]], ""</a>"")"
This formula produces an Error during preview, for reasons I could not figure out. I suspect that it is importing extra double-quotes. I understand the intent of the import was to enable certain excel functions, but in this case it does not seem to work. The only workaround I have is to create a new column that contains only the interpreted contents of the formula column (by copying and pasting contents into a new column), and then import that. This extra step does not cause enormous work, I just have to manually clean up the table and delete the formula column.
I just wanted to report this as an issue since it may be that you could make a change to make the formula for concat work like it does in excel, to the benefit of all users, or perhaps you can provide an option for importing Contents rather than Formula for a column or better yet the entire import.
Thanks for a great product, just trying to make it better!
