I’m struggling with plus sign (+) . when I type a text begin with “+” on appsheet , I notice that corresponding cell on googlesheet is turned to a formula#ERROR! !!!
I have this problem only with the sign (+) but in contrary the sign (-) googlesheet adds automaticlly an apostrophe ’ to avoid turning the cell to a formula
I change the format of the sheet from number to plain text but I still have same problem .
I replicated exactly what you observed. I formatted the sheet column as plain text, and no apostrophe was prepended or necessary for the value beginning with a minus sign. While the value that begins with a plus sign is retained in the sheet, the resulting error means it’s unavailable to the app. If you didn’t already, I suggest at least report to AppSheet Support, although it may not be fixed anytime soon–especially since this is a data source (i.e., Sheets) issue rather than an AppSheet issue per se.
Meanwhile, if you can’t avoid values that begin with a plus sign, you could experiment with workarounds like this quick, untested brainstorm:
Create a shadow column with an Initial value that prepends a character to the value you need to save in the data source (e.g., "X" & [text column]) and Reset on edit triggered whenever your text column is updated.
Create another shadow column that’s virtual with an App formula that removes the prefix (e.g., RIGHT([text column], LEN([text column]) - 1). Use this column wherever you need your original column’s intended value for display or expressions.
And, actually, here’s another quick, partially tested idea. Either manually or automatically insert an apostrophe into the value. It looks like that gets suppressed once it’s saved to Sheets, and that’s reflected back to the app.
