Comment 8 Bartosz 2016-12-10 23:09:21 UTC
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".
