SheetJS
e1f8dbb863
- read BOM, handle UTF16LE-encoded XML - handle namespaces in [Content_Types].xml - parse workbook rels to determine sheet files - numbers OSX boolean support (apparently requires "0" or "1") - XLSX force "General" style to be serialized, omit implied cell type and style - updated SSF to 0.7.0 (h/t @sysarchitect) - updated jszip to 2.2.2 - removed old tests/files path, replaced with test_files - themes written - ignore potential existence of thumbnail when calculating relationship ids
