The black squares in the four corners are required for scanning; do not cut them off or write over them.

1. 1Write the number in the box and fill in the digit under each column.
2. 2If the number is shorter than the number of digits, you can leave the leading or trailing digits empty or fill them with 0: "00321", " 321" and "321 " are all saved as 321.
3. 3Do not leave an empty digit in the middle; an unreadable digit is shown as "?" and you will be asked to correct it.

2. 2Use "Import from file" to choose an Excel (.xlsx/.xls), CSV or e-Okul list. The columns are recognised from the headers "School No" and "Full Name" (or "First Name" + "Last Name").
