FAQ
Frequently asked questions and answers.
How long can strings be in cell storages?
Up to 4000 characters.
If my Excel template contains a VBA macro, does it run in Nooxl?
No. Macros are neither executed in Nooxl Apps nor included in exports — both are disabled because of the security risk. For programmatic logic, use a cell action section instead.
Why are cell borders not displayed as in Excel?
Nooxl Apps renders cells as an HTML table, where two adjacent cells share a single border. Borders are assigned like this (assuming the visible range/tab starts at A1):
- A1: all four borders are rendered.
- Row 1 from column B: all borders except the left.
- Column A from row 2: all borders except the top.
- All other cells: only the right and bottom borders.
Borders are rendered even if none was set in Excel — in that case they take the cell's background color.
This does not apply to the right border of merged cells: it is not rendered and always appears white, which can cause "staircase effects" where borders meet.
With what precision are numbers stored?
Excel's maximum precision is 15 digits in total. Nooxl Apps stores up to
15 digits before the decimal point plus up to 14 digits after it (before November
2019 only 4 after). Values greater than 10^16 − 1 require database adaptations
(decimal [29,14]).
