Automating a shopify item creation upload file

I am looking to automate the process of uploading new item information into my Shopify store from supplier-provided files. Currently, I receive a CSV or Excel file from my various suppliers containing the item names, descriptions, affiliated picture URLs and other relevant product details. However, this format cannot be directly imported into Shopify for creating new item listings. I need a freelancer well-versed in web scraping and Shopify APIs to programmatically parse the supplied files and transform the item data within into the appropriate JSON format specified by the Shopify item creation API endpoint. The transformed data should then be uploaded in bulk to my store via the API to generate all the corresponding new product listings. Experience with Shopify and familiarity with common product data formats is essential. The goal is to develop a seamless process that can automatically ingest new item uploads from my suppliers and populate my online store in a structured and organized way without any manual data reentry.
