When a historical query is placed on an Excel spreadsheet, ExcelTools uses a "field ID" to identify the data to place in the cell. When using Plain or Bold Headers, the header identifies the data field:

When using Hidden Headers, the Field ID is embedded in the function. In this example, "Open" is the Field ID:

- Fields have a number of alias names. "Last", "Last Price", " p", "price", "lastprice" all reference the same data.
- Field IDs can be entered with capitalization or lowercase. "Open Interest", "open interest", "Open interest", and "OPEN INTEREST" are all used to reference the same data.
- Use of a space between words is optional. "MID POINT" and "MIDPOINT" reference the same data.
