This applies to both creator and the online tools. The excel converted from the pdf always ends up having error when I try to open it, and upon opening it always displays the similar type of error:
Removed Part: /xl/sharedStrings.xml part with XML error. (Strings) Illegal name character. Line 1, column 263.
Removed Records: Cell information from /xl/worksheets/sheet1.xml part
Removed Records: Cell information from /xl/worksheets/sheet2.xml part
Removed Records: Cell information from /xl/worksheets/sheet3.xml part
...
and so on.
The funny thing is, the very same PDF worked hours ago! I managed to convert it to excel with 300+ sheets using the online tools. Then now suddenly it doesn't anymore, and I don't know what exactly have I done that caused the change, the pdf wasn't edited at all. I tried using other converters and those still work as per normal but the formatting of the multiple sheets aren't nearly as consistent as what pdf24 achieved, and somehow only pdf24's converter doesn't work for me now.
