What sort of application should I build to process data files ?

Hi All,

I'm in the process of building a VBA application which will take a number of data files from different sources (.csv, .txt, Access database) and consolidate them into a single Excel worksheet. I will want to do some basic validation on each input file, depending on its source, prior to copying the data to a worksheet.

Where would you start with this ? How should I execute the VBA procedures ? From an Excel workbook itself ? If so, would you suggest a User Form interface, or a worksheet, or an event ? Or is there another way of running a VBA application ?

I'm open to ideas but my programming knowledge is limited to Excel VBA.

I think you answer your own question.
If your knowledge is limited to just excel VBA then that should be the application to use.
It is more than capable of what you need, so why go to the trouble of using something else.

Start with an excel workbook and use it to open the files.
A user form is likely not necessary.
It all depends on the tasks required.

1. you can pull data into a workbook
2. you can push data into a workbook
3. you can use VBA or VBScript to 'package' your coode
4. you can do basic file I/O or use ADO to treat the data sources as tables

I think that some of our recommendations might depend on what kind of validation you need to perform.

Thanks Steve for your advice. It may be the most practical solution for me.

Aikimark, can you explain Pull and Push a little more please ? How would I 'package' my code ? What do you mean by 'basic file I/O ?
