Sheet Visibility
Excel enables hiding sheets in the lower tab bar. The sheet data is stored in the file but the UI does not readily make it available. Standard hidden sheets are revealed in the unhide menu. Excel also has "very hidden" sheets which cannot be revealed in the menu. It is only accessible in the VB Editor!
The visibility setting is stored in the Hidden property of the sheet props
array. The values are:
| Value | Definition |
|---|---|
| 0 | Visible |
| 1 | Hidden |
| 2 | Very Hidden |
With https://rawgit.com/SheetJS/test_files/master/sheet_visibility.xlsx:
> wb.Workbook.Sheets.map(function(x) { return [x.name, x.Hidden] })
[ [ 'Visible', 0 ], [ 'Hidden', 1 ], [ 'VeryHidden', 2 ] ]
Non-Excel formats do not support the Very Hidden state. The best way to test
if a sheet is visible is to check if the Hidden property is logical negation:
> wb.Workbook.Sheets.map(function(x) { return [x.name, !x.Hidden] })
[ [ 'Visible', true ], [ 'Hidden', false ], [ 'VeryHidden', false ] ]
