"bug 12345 - Can't save foobar-encoded video to DOC file"
Bug 75167 - Tools | Options | LibreOffice Calc | Calculate | Enable Regular Expressions in formulas setting not saved
LIMITATION: Calc does not save Regular Expression settings in a format of spreadsheet that is incompatible with Excel (Excel does not support Regular Expressions).
Migrating Whiteboard tags to Keywords: (filter:xlsx)
FORMATTING: User Defined Custom Formatting is not applied during importing XLSX documents:
Bug 104186 was added to the "Depends on" section of bug 88175.
In my opinion this is incorrect as bug 104186 describes a failure to comply with the existing XLSX (ECMA-376) format. In my understanding this is not a "limitation" of the format as stated in the title of bug 88175 but a plain and simple bug.
Is this something you could take a look at? Thanks!
OOXML format supports only 6 arrow ends:
None, Triangle Arrow Head, Stealth Arrow, Diamond, Oval and Arrow Head
Bug 61148 OOXML doesn't support border thickness, other than: 0.75 (Medium) and 1.75 (Thick):
Bug 62878 is an limitation of the OOXML format. The indentation is saved in .xlsx, as integer value, where an increment of 1 represents 3 spaces.
It means that minimal identation width is 3 spaces. Unfortunately we cannot do much to fix that bug.
I guess Bug 58375 goes here.
LO Calc has "Hyphenation Active" with Format-Cells-Wrap and MSO Excel doesn't have that option. I don't see Hyphenation in "18. SpreadsheetML Reference Material".
