I've added a splutter to the core:

\startluacode

local mycsvsplitter = utilities.parsers.csvsplitter {
     separator = ",",
     quote     = '"',
}

local crap = [[
"1","2","3","4"
"a","b","c","d"
]]

local mycrap = mycsvsplitter(crap)

context.bTABLE()
     for i=1,#mycrap do
         context.bTR()
         local c = mycrap[i]
         for i=1,#c do
             context.bTD()
             context(c[i])
             context.eTD()
         end
         context.eTR()
     end
context.eTABLE()

\stopluacode
