            Bug ID: 116425
           Summary: FILEOPEN XLSX Excel spreadsheet takes forever and a
                    lot of CPU time to open
           Product: LibreOffice
           Version: 6.0.2.1 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: clogged.drainpipe at gmail.com

Description:
Here I have a spreadsheet that Calc absolutely chokes on. Just opening the file
take about 2 minutes of CPU time, while Calc is completely unresponsive. Even
after the document is open, all operations are very sluggish and Calc
repeatedly locks up and stops responding for many seconds. MS Excel 2016 has no
problems opening the file under 10-20 seconds.

Steps to Reproduce:
1. Try to open attached document
2. Observe that it locks up, uses 100% of one CPU core, and after a long time
it opens the document
3. Observe that any attempted operation in the document can take a very long
time

Actual Results:  
The file takes forever to open and locks up LO for extended periods of time

Expected Results:
The file should open quickly, without excessive CPU usage. LO should not lock
up and stop responding while loading the document.


Reproducible: Always


User Profile Reset: No
