  We introduce PineAPPL, a library that produces fast-interpolation grids of
physical cross sections, computed with a general-purpose Monte Carlo generator,
accurate to fixed order in the strong, electroweak, and combined
strong-electroweak couplings. We demonstrate this unique ability, that
distinguishes PineAPPL from similar software available in the literature, by
interfacing it to MadGraph5_aMC@NLO. We compute fast-interpolation grids,
accurate to next-to-leading order in the strong and electroweak couplings, for
a representative set of LHC processes for which EW corrections may have a
sizeable effect on the accuracy of the corresponding theoretical predictions.
We formulate a recommendation on the format of the experimental deliverables in
order to consistently compare them with computations that incorporate EW
corrections, and specifically to determine parton distribution functions to the
same accuracy.
