Using '*' in SQL FROM statement to access Excel cell range

Question

I have a script that converts an .xlsx file to .csv file but this script uses a cell range in Excel to read the data. The script is working but I wish to expand it to prevent possible user-bugs.

The query to select a Excel cell range (in SQL ):

  string query = "SELECT * FROM fileName";

What I'm trying to do is make the script select an 'ALL' kind of range so that if a user changes the filename it still works. Like this:

  string query = "SELECT * FROM User_*";

User_ will be standard for every document but what comes after the _ can be changed by the users. Using * is not accepted as ALL in this case, and I can't seem to find something that works.

Answer 1

I used another script to run an Excel macro on the document before converting it. This macro changed the name of the cell range to a common name that is now used to convert the document.
