vba - Why are EXCEL XLSM format no longer a valid ZIP format? -


files saved in excel xlsm files no longer valid zip files, preventing editing of ribbon.

xlsm files saved on or prior may 23, 2014, can renamed .zip , edited.

xlsm files saved after may 23, 2014, cannot renamed .zip , edited, rather generate error message file corrupted archive. both windows explorer , winzip generate same error condition, though error message varies slightly.

yes, there macros in files; opening old file macros (and vba) disabled , saving new name generates corrupted file.

i have tested on 2 other machines in our corporate group, same results, not corruption on workstation.

office diagnostics reports no problems excel.

any thoughts on causes or solutions?

update

let's clear on test process:

  1. i rename xlsm file saved on may 23 .zip; creates zipped archive both winzip , windows explorer can open successfully. undo rename make file xlsm again.
  2. i open file above in excel-2007 and not enable macros or vba. save new filename xlsm file.
  3. i rename file saved in step (2) .zip file. file no longer opens in either winzip or windows explorer, generates error message above.
  4. i repeat steps 1 through 3 above on workstations of 2 other colleagues - same result exactly.

update #2
problem seems file-related in way, saving empty workbook xlsm still works. investigate more.

the problem 1 or more of sheets password protected. unprotect sheets, save xlsm, rename .zip , voila, xml structure appears.

update: actually, inconsistent setting of password-protection workbook rather worksheet.
