Created attachment 118873 [details] Comparison HTML Page and sample excel files On the website of softmaker office a couple of years there were a comparison between excel, their planmaker an openoffice 2.0. With the release of libreoffice 5.0 i checked if the issues are still valid. Unfortunately a lot of issues are still open. a couple of issue are regarding positioning of elements, some are regarding missing data after import, some are releated to missing chart elements. I saved the whole comparision page with all the sample documents. may these excel files help you tracing the cause. Regards
AutoShapes: bug 49881 (regarding them in general) WordArt: bug 51672 Array functions work ok. Charts: looks buggy, don't remember a report, might be hard to find Radial charts: looks slightly buggy, don't remember a report and can't find one Charts with legends: I have seen a report for this Surface charts: can't remember a report for this Additional charts: I have seen a bug report for that same file (maybe many) All in all, it seems like this comparison is quite well known and I believe all of these files have bug reports. I will set this to invalid, but I am happy you want to improve the quality of LibO. I urge you to continue as we are always looking for more volunteers. Here you will find the detailed instructions on testing bug reports: https://wiki.documentfoundation.org/QA/BugTriage IRC is a good way to communicate with other QA people: https://wiki.documentfoundation.org/QA/IRC
