Number formats that contain double quotes generate bad styles.xml in the .xlsx file

[snoopyjc]

Number formats that contain double quotes generate bad styles.xml in the .xlsx file. For example:

mso-number-format:"\#\,\#\#0\.00\;\[Red\]\0022-\0022\\ \#\,\#\#0\.00";

generates:

<numFmt numFmtId="165" formatCode="#,##0.00;[Red]"-"\ #,##0.00"/>
