How to get and fix raw value of a cell that has #ERROR

问题

I have a problem when copy-pasting table data from a web page into Sheets, that the cell values which start with an equals sign ("=") and has wrong decimal delimiter (",") for the locale, for example

=+90,00

causes Sheets to complain about #ERROR! - Formula parse error.

Because I cannot change the source of the data easily and there is a lot of it, I cannot manually remove or change the characters that break the value thinking it is a formula.

Therefore I have been looking for ways to get the cell contents raw to another sheet cell while removing the extra characters.

E.g. on a sheet named RawSource cell A1 I have value (formula)

=+90,00

that causes #ERROR! on that cell. On the destination sheet I tried this formula to fix the error by removing the first character (equals sign):

=RIGHT(CELL("contents", RawSource!A1), LEN(CELL("contents", RawSource!A1))-1)

But no luck so far since I think the ERROR value is propagating even through the CELL function and not the raw contents of the cell.

Is there any way to fix this without manually altering the source data?

回答1:

once you imported an #ERROR! it can't be corrected by another formula, because that used formula can't see behind that error. workarounds are:

if you import such data with IMPORTHTML / IMPORTXML / etc. wrap it into REGEXREPLACE or SUBSTITUTE and in some cases even in TO_TEXT with combo of ARRAYFORMULA to get rid off error causing cases
if it's pasted (as in your case) your only option is to manually add ' upfront of every error cell (eg. '=+90,00)
also you can always try to paste it in a sheet with a different locale (French, Spain, Czech, etc.) and then copy-paste it to your sheet from there

If this is something that you will be doing once on while, consider the following procedure

Create a new spreadsheet
Change the regional settings to one that use comma as decimal separator
Import your data that use comma as decimal separators
- The trick here is that Google Sheets will interprete the imported formulas as having a valid number
Copy the values to a spreadsheet that use dot as decimal separator

Another alternative is to use Google Apps Script in order to be able to get the formula as built-in formulas can't see the formulas, just their results or cell properties, i.e. there is built-in function to check if a cell has a formula, ISFORMULA, but there isn't one that return the formula.
