I got the exception when i opened this https://yadi.sk/d/9RC1JcPY3S2kHa xlsx document template

null: RangeError: Invalid time value
message: "Invalid time value"

I did this dirty hack and now everything works fine

  this._format = options.format || function (dt) {
    try { return dt.toISOString(); }
    catch(e) { console.log(e); return '' }
  };

I don’t know why it’s happening because i’m newbee in js and don’t have enough time to understand exceljs lib at all.

My current solution is to make a template through the google documents.

I had the same problem, this error will happen when you use datejs in exceljs options.
