Data Loading, but much Better
I think we can assume you've used a Data Loader before, and you're here because you want a tool that can do more. For any newbies, though, FuseKit's Data Loader can be used to create, update, or delete records in Salesforce (much quicker than editing each record individually!)
Like the Query Builder, the Data Loader is pretty simple to use.
Pick your object, upload your file (pretty frequently, you'll have generated the file via the Query Builder), and choose whether you want to insert, update, upsert, or delete the records. Pro tip: Upsert is used when you are either inserting or updating records. Get it? Up(date) + (in)sert = Upsert!
The moment we've all been waiting for...
At this point, FuseKit will auto-map any of the fields that it can figure out, but you can remove or change these as needed. Once you get those sorted, you can toggle any of the options you want (most users just leave the defaults 🤷♀), and bum dum dum dummm!, hit Load Data!
After it processes, you can download the success and/or failure results. Success results will show you the Ids of the newly inserted records, and Failure results will give you an error message explaining what you need to fix. Most of the time, you can just quickly fix the error in the Failure file and do a quick re-load to get 'er done.
