Hello,
Interested in the project.
I am a Software Engineer with expertise building solutions that leverage Google Apps Script - GSuite's (which includes Google Sheets) native scripting language.
I can create a series of scripts that can export your product list from your Google Sheet to your Shopify account via Shopify's APIs. You'll be able to use this tool whenever you need to import product listings into Shopify.
1. CSV (Comma, Separated Values) are a standard data exchange format that I have worked with extensively over the years. I have not worked specifically with Shopify's Product List format but I've read the format specification; its straightforward and will not present me with any difficulties.
2. I should be able to build this tool within a few days, at most 5. Depending on how your spreadsheet is structured I might be able to build this tool within a day; if its more complex, with data spanning multiple sheets, it will take longer.
Note that this is a script based solution. Once created you'll have a tool that you can apply to future product listings when you need to import new products.
Thank you for taking the time to review my proposal and I look forward to discussing your project in greater detail if afforded the opportunity.
Regards,
Damion Murray
