R1C1 vs A1 notation, how so say RC[-1] in A1 notation

Yeah, I tried it, it works as promissed.
Thanks,

Ah, I misunderstood the question. I suggested to replace

    Formula_Convert(oCell, sFrom, 2)

with

    Formula_Convert(oCell, sFrom, com.sun.star.sheet.AddressConvention.XL_R1C1)

because magic numbers are much worse than mnemonic constants, even such longish.

…anywhere i define P(x|y) position shifting without macro coding:
