XLS transfer to xml

I'm looking for a freelancer to create an XML file from an XLSX file. The XLSX file is a simple single worksheet file with no formulas. I have a specific structure in mind for the XML file it needs to be compatible with Zoho , so the freelancer should be able to follow the provided structure without deviation. The freelancer should be experienced in both XLSX and XML file formats in order to ensure accuracy and a satisfactory outcome. I am ready to discuss project details, timeline and cost structure with interested freelancers.
