To use Google Sheets, you need to follow a few rules for using your spreadsheet.
Spreadsheet formatting
Any spreadsheet you use in your Jicoo must:
Include headers in the first row. Clearly label each column with a descriptive name in the first row. This will tell Jicoo where to send or receive data from.
The column ID is reserved. It should not be used for other purposes as it will be the column where Jicoo's booking event IDs are stored. If the ID column is not present in the header, Jicoo will create the ID column in the leftmost column.
