We can't read the data from xlsx file 'as is', meaning that I want to use string fields in my metadata to read the data and validate them in Validator afterwards.
The problem is that we if the excel file contains i.e. 12.3456, MS Excel displays the value as 12.34 as the rest is hidden by used cell formatting.
It can be adjusted using Text (and others) formats but that's not always feasible for the customer.
We should be able to read the raw data as string, at least with some additional option in metadata format property, i.e. excel:raw.
Interesting thing is, that if I play with the format, it turns out that the complete data/number IS actually available, see the 71428.001500002996 value in the error:
