Importing values to custom sheet

Sorry if this has been asked before, i couldn't see anything particularly relevant already in the forums. If i have a custom sheet with empty values, like lets say all the core stats are just named fields, is there a way to import values to fill out that sheet? i have a separate website where the values are being kept, and i could have that website create the script to enter the values dynamically, but i can't really figure out where i would have players input the generated script to have their stat values imported, or if that is even possible.

An API script could be written to handle this off-sheet, or perhaps done on-sheet internally using a textbox field for input and sheetworker to process.  Export from your external location as a json, paste into the sheet, then use sheetworkers to parse the json (basically, match json key to a sheet attribute and set the attribute to the json value).  Easy-peasy.  I'm not qualified to actually demonstrate how to do this in js/sheetworker though. ;-(  But , perhaps someone else might be able to post an example...

You might be able to do it without a script, by having your website write a bunch of command lines for chatSetAttr, a script that lets you edit and create attributes for a character.

Here are some examples of using this technique to write custom class features on the Shaped Sheet and custom Equipment on the OGL sheet .

You also export the data in JSON format, and set up a field on the sheet where you paste the JSON (or any structured format, really) and have a sheet worker parse the data. 

thanks yall, that was really helpful!
