Sounds like a mixture of the sc file format and BASIC:

    let A0 = 123 
    let A1 = 234 
    let A2 = 345 
    rightstring B3 = "asd"
    leftstring B5 = "foo"
    label B11 = "bar"
    goto B11 A0

Just a textual description of what your spreadsheet should look like. Gosling had it right back in the 80s ;)
