A simple program that I can point to a DAT and it will analyze it for issues like columns not lining up,
|
| 10 |
|
|
what fields they gave in the headder and which ones have stuff and which are totally empty, etc.
|
| 11 |
nino.borges |
687 |
Support for UTF quotechars and delims plus removing that little BOM at the beging added.
