How Does An Usb Refrigerator Works

Validate RUC

Often we are asked to validate cells, which restrict certain features, for example in this case we are asked to validate a cell to enter 11 digits of the number of RUC, the idea for this would be the following:

= Y (ISNUMBER (C3), LEN (C3) = 11)

This type of validation restricted to the cell C3 can only enter numeric values \u200b\u200band 11 digits.
