Hello,
I can do it. I can create an Desktop App through which you can upload the sheet and sheet's data will pass to the Zoho CRM through Zoho API.
I specialize in Zoho API. I successfully integrated this API into various projects.
I have integrated Zoho API with Signable API in the recent [login to view URL] integration saved client's time as now he didn't have to create a contract manually.
I will need your Zoho API Key to start the project.
What you will get, if you hire me:
1. Fully commented out source code of your project
2. Detailed document on project completion , it will include all logic , database schema & file details of the project
3. 1 year free technical support (Call / Email / Skype) , if any issue arises.
Please provide me with more details & let’s get it done.
Thank you for your time.
