Question

How can I convert multiple html tables to an excel sheet with multiple worksheets? Could you please help into this.

Answer 1

Here is a better solution that supports exporting table in the latest Excel format i.e. xlsx . The accepted solution would fail in case the total number of rows being exported exceeds 3407 on Chrome.

Save XLSX file

javascript

window.saveFile = function saveFile () {
var data1 = [{a:1,b:10},{a:2,b:20}];
var data2 = [{a:100,b:10},{a:200,b:20}];
var opts = [{sheetid:'One',header:true},{sheetid:'Two',header:false}];
var res = alasql('SELECT INTO XLSX("restest344b.xlsx",?) FROM ?',
                 [opts,[data1,data2]]);
}
