Unlock cells in grey

Hi,

I have a sheet that after the column "X" there are no more columns and in place a grey area. The rest of the columns/cells are hidden.
I've unlocked all the cells of the sheet and it isn't protected with a code, so i don't know how i can unlock it to be showed...

I've attached the file....

Can anyone help me?

Hello, selects entire line and menu -> Format -> Columns discover.

Hi,

Thanks! It worked!
How can i do the inverse way? Lock all columns except A to X?


Thanks

To lock columns, if they are consecutive, then select all columns menu -> Format -> hide columns.
For a single column, select only the column and do as said before.
