At Quantec we regularly need to convert file formats of our data. To make this process as painless as possible we have been using Stat/Transfer by Circle Systems. The new version 11 supports even a wider assortment of file formats (including the new Stata 12) and is now available as a native 64 Bit Windows application under the same 32 bit license.

If you looking for a 'swiss army knife' application, capable of converting a vast selection of file formats, give Stat/Transfer a try.

The latest version 11 is available from Quantec.
