The exclusive electroproduction process $ep \rightarrow e'p'\pi^{0}$ wasmeasured in the range of photon virtualities $Q^{2} = 0.4 - 1.0$~GeV$^{2}$ andthe invariant mass range of the $p\pi^{0}$ system of $W = 1.1 - 1.8$~GeV. Thesekinematics are covered in exclusive $\pi^{0}$ electroproduction off the protonwith nearly complete angular coverage in the $p\pi^{0}$ center-of-mass systemand with high statistical accuracy. Nearly 36000 cross section points weremeasured, and the structure functions $\sigma_T+\epsilon\sigma_L$,$\sigma_{LT}$, and $\sigma_{TT}$, were extracted via fitting the$\phi_{\pi^{0}}$ dependence of the cross section. A Legendre polynomialexpansion analysis demonstrates the sensitivity of our data to high-lying $N^*$and $\Delta^{*}$ resonances with $M~>~1.6$ GeV. As part of a broad effort todetermine the electrocouplings of the $N^{*}$ and $\Delta^{*}$ resonances usingboth single- and double-pion electroproduction, this dataset is crucial for thereliable extraction of the high-lying resonance electrocouplings from thecombined isospin analysis of the $N \pi$ and $\pi^{+}\pi^{-} p$ channels.
