When you translate a pricing table the decimal comma might change to a decimal point. E.g. German to English. Even when i changed the language of the file to english, there was no way for me to change the decimal comma to a decimal point. I used a GREP search and replace for that. But as soon as the linked excel table updates, i have to remember to do the GREP search. I managed to change the decimal seperator in excel, but indesign seems to override it by using the systems language.
