Heavy handed approach adds text wrapping to all cells exported by SheetJS library

xlsx.mjs

/**
 * Heavy handed approach adds text wrapping to all cells.
 * Doesn't seem to break anything for other field types….
 * Haven't thoroughly tested.
 * New:
   <cellXfs count="2">
	<xf numFmtId="0" fontId="0" fillId="0" borderId="0" xfId="0" applyNumberFormat="1">
		<alignment wrapText="true"/>
	</xf>
	<xf numFmtId="3" fontId="0" fillId="0" borderId="0" xfId="0" applyNumberFormat="1">
		<alignment wrapText="true"/>
	</xf>
   </cellXfs>
   
   Old:
   <cellXfs count="2">
	<xf numFmtId="0" fontId="0" fillId="0" borderId="0" xfId="0" applyNumberFormat="1"/>
	<xf numFmtId="3" fontId="0" fillId="0" borderId="0" xfId="0" applyNumberFormat="1"/>
