My questions:
1. Does the CSV tool require one to have columns of data with headers or is it possible to pull only specific cell data from a single cell in a ".xls" spreadsheet (or from multiple singular cells)?
It works on a table. All columns must have a header. Think of it as one column per snippet. Each line in that table would align with a different topic.
2. Do I still need to "save as" the ".xls" spreadsheet into a CSV file so this tool can read the info or does the CSV tool read .xls data also?
You can save as XLSX or CSV
3. Is it possible to overwrite data when a character or NPC increases in level? Meaning can I just import the same character over and over again or would I need to delete the RW snippets/character entry every time someone goes up a level?
No this will not work as the tool does not save unique UUID's for future use. It creates a new one for each snippet during the import process.
