Thanks a lot. I have a series of strings like : Glass unit formula 4х10(Пл+Ar)х4х10(Пл+Ar)х4ТорN+ R-value - 0,77 m² • С/W - so the same one like showed above.
I also have"Thermal conduction = 0,038 W/mK" should I use the find function twice?
=TRIM(MID(A1,FIND(",",A1)-1,5)) will work for the three examples that you shared with us.
Thanks. What about: "Thermic power 21-40kW efficient factor 77,6-77,8%"
btw. slowly I start to understand these functions.
