{%macro display_csv_fields()%}
Provide the character that separates the fields in your file(s). It should be the same character for all files (if more than one is provided).
A tab character will be assumed if you leave this field blank. See documentation for more information.
This specifies that lines that begin with the character(s) provided will be considered comment lines and ignored in their entirety. See documentation for more information.
This specifies strings in your file indicate that there is no value for a particular cell (a cell is where a column and row intersect). Provide a space-separated list of strings if you have more than one way of indicating no values. See documentation for more information.

File separator
The files you provide should be character-separated value (CSV) files. We need to know what character you used to separate the values in your file. Some common ones are the Tab character, the comma, etc.
Providing that information makes it possible for the system to parse and process your files correctly.
NOTE: All the files you upload MUST use the same separator.
Comment characters
We support use of comment lines in your files. We only support one type of comment style, the line comment.
This mean the comment begins at the start of the line, and the end of that line indicates the end of that comment. If you have a really long comment, then you need to break it across multiple lines, marking each line a comment line.
The "comment character" is the character at the start of the line that indicates that the line is a line comment.
You can provide more than one comment character, separated by spaces.
No-Value indicator(s)
Data in the real world is messy, and in some cases, entirely absent. You need to indicate, in your files, that a particular field did not have a value, and once you do that, you then need to let the system know how you mark such fields. Common ways of indicating "empty values" are, leaving the field blank, using a character such as '-', or using strings like "NA", "N/A", "NULL", etc.
Providing this information will help with parsing and processing such no-value fields the correct way.
