  The $\Lambda_b \rightarrow \Lambda_c \ell^- \bar{\nu}_\ell$ process has been
discussed in the literatures as a probe for new physics. This process receives
contributions in new physics models from scalar, vector, and tensor hadronic
currents. The form factors of these currents can be obtained from the quark
model or the lattice QCD. In this work, we present a c-code to read the scalar,
vector, and tensor lattice QCD form factors. A Mathematica code was used in
Ref. \cite{Datta:2017aue} to read the form factors. Our c-code is much faster
than the Mathematica code where the ratio of the wall clock time for the c-code
compared to the Mathematica code is 1:64.2 per data point.
