I am new to Monday.com we have a trucking company, Dump trucks to be exact and we Haul all kinds of aggregates, sand, and gravel for construction projects across Eastern North Carolina. I have a ton of Historical data that i want to put into the platform. I am struggling to see how monday can help streamline my work. I keep hitting walls and sometimes it feels very boxed in. Here is an example, just WHY? why is this even an un supported action? Surely the devs can make this happen to import into the columns i have setup. Am i missing something? This seems super basic as a feature.
Hey Mark! 
Thank you for sharing your feedback with us in the Community–I hear you. Importing via Excel or CSV can be frustrating when users are limited to syncing their data to a Text, Status, Date, Numbers, or Phone Column. I see that you have already dedicated time to build out all of your columns prior to the import as well.
I wish I could give you an immediate solution here! This is a common pain point for many new users. I encourage you to upvote this ongoing feature request here: Excel Import in Board - Greater column support.
With more votes, our Product team can continue to prioritize this feature on the Product Roadmap.
