A datawarehouse project required documentation for incoming CSV-files. The intent was to list all header fields of tens of CSV files grouped by the file name.
Instead of typing field names routinely one by one to our documentation, I automated the task using Python code. The Python code loops through all CSV files in chosen directory and generates a new text file, where all field names are listed for each CSV file.
