Issues with Google Sheets formulas

When you create an AppSheet application from Google Sheets, AppSheet does the following.

1. Asks Google Sheets to export your Google workbook as an Excel .xlsx file.
2. AppSheet uses an Excel library to read the contents of the exported .xlsx file. This allows it to extract the cell data values, cell formats, cell formulas, and other values from each worksheet in the exported .xlsx file.  
3. In the case of formulas, AppSheet converts the formulas from A1 format to R1C1 format. It is easier for AppSheet to interpret formulas in R1C1 format. AppSheet can more easily determine if a formula is accessing values in other rows. To learn move about R1C1 formulas see A1 versus R1C1 formulas.
4. AppSheet uses all of the information extracted from the worksheet to infer the attributes of each column in the worksheet. AppSheet uses this information to determine the name, type, precision, formula, and other attributes of each field in the table created from the worksheet.
5. AppSheet does this when you first add a table that is based on a Google Sheet and repeats this each time you click Regenerate. 

Fortunately, the vast majority of Google Sheets formulas can be translated into equivalent Microsoft Excel formulas. Unfortunately, some Google Sheets formulas have no Microsoft Excel equivalents. These include:
