Transferring data to excel truncates data

Hello,

We want to transfer some data (stock transfer draft) to excel format. However when doing this, the numeric fields are incorrectly transferred to excel. For example, if we have in the system field "Quantity" the value:

1,000.0000 (one thousand)

then that value is transfered to excel:

1 (one)

Do you know how could be this avoided?

Thank you.
