Hi,
I checked your requirements and I can convert the excel,csv,ods file to json with appropriate mappings & make ajax call. The file contents will be rad using HTML5 file reader api & parsed using js-xlsx library([login to view URL]) so that no data will be sent to server. Once the user selects mapping, It will be sent as json.
Pls DM me to discuss further details.
I have 4 years of experience in front-end devlopment using HTML, CSS, JS, jQuery, Bootstrap and AngualarJS. I
am proficient programmer in asp.net and php also. I can assure you that I will provide quality work in given time
period without any issues. The final code will be delivered with comments and documentation.
Looking forward to work with you,
Kasi
