XLSXML

AlaSQL has XLSXML() export function with coloring functionality:

var data = [{city:"London",population:5000000}, {city:"Moscow",population:12000000}, {city:"Mexico",population:20000000}, {city:"New York",population:20000000}, ];

var opts = { headers:true, column: {style:{Font:{Bold:"1"}}}, rows: {1:{style:{Font:{Color:"#FF0077"}}}}, cells: {1:{1:{ style: {Font:{Color:"#00FFFF"}} }}} }; alasql('SELECT * INTO XLSXML("restest280b.xlsx",?) FROM ?',[opts,data]); Here you can define style for any column, row, or cell in the sheet.
