We get different font sizes in exported xls and xlsx files. And we get font sizes in xlsx that do not match the size defined in jrxml definition. Also in xlsx font sizes defined on cells are different from font sizes defined on characters in cell. We tried with font fix on and off, and there is no difference in output. And we tried with html markup and no markup.
JRXlsExporter gets the font sizes right but doesn't interpret colors defined with html markup, that is why I have to use JRXlsxExporter
We tested this on JasperReports server 4.7 and 5.0.
Does anyone knows how to fix this or is this a bug?
