I understood that you have a file with 27 spreadsheets (tabs), if yes, just select all tabs and make the change in the first visible, the others assumed the applied formatting. To separate them, just click on any tab without being the first.
Follow this procedure: If the tabs are all in sequence > Click on the 1st tab, press Shift + last tab desired. // If the tabs are not sequential > Click the 1st tab, press Ctrl + desired tabs. Then do the desired formatting in the active tab (anything you do will be replicated on all selected ones), at the end click on any other tab to separate them. (Performed in Win7 + Libo 5.3.5.2)
Tried with macro? if they are equal the process of one is the same for the rest. That way I believe the question is on topic since it has something programming.

@rray think that openoffice does not accept macro.

@Articuno has yes, some things not compatible with MS office also depends on the OO version or if it is libreoffice, broffice etc.

I asked here because I thought there would be some macro that could be done, so I asked in the programming topics.
