A file checker utility for file based data sources
During development few cases you may find your data source as bunch of excel files. Sometimes you may find those spreadsheets either in bad format or missing required fields. Sometimes it is difficult to trace all those files where you have missing fields, if the number of data source files are huge. It is also very difficult to identify the missing fields from the log as the "Field not found error" just indicates the first missing Field not all the missing fields in a specific file.
I've attached a document here that has a use case of how a program can be created to handle the missing fields in a file.
The document provides a sample code which can be use to create a table that can hold the File name, File Reload time and the list of Missing fields in that file.
