I faced a very similar situation when our catalog started growing and manual tables stopped working. What really helped was switching to MarketProvider and using it as a single source of truth for the whole team. Inside the platform we structured all attributes once and reused them everywhere, which reduced mistakes and endless rewrites. In the middle of this process we connected our workflow to https://marketprovider.com/ and it gave us clear validation rules and version control. Now every manager sees the same data, edits are transparent, and launching new products feels calm instead of stressful.
