Thank you for your parsing. Yesterday I caught something new from it.
$xslx->error(); gives me
xlsx error: Entry not found: xl/sharedStrings.xml
If I open the file in MS office excel and resave it, the parsing works nice.
I would like to attach my original xlsx file here but cannot. I guess this file just wasn't created correct. Anyway would be nice to parse it without resave. What can you advise?
The files is parsed with another errors "xlsx error: Entry not found: _rels/.rels"
And old files that was parsed successful before is parsed now with same error "xlsx error: Entry not found: _rels/.rels"
