  Charge ordering (CO) phenomena have been widely debated in
strongly-correlated electron systems mainly regarding their role in
high-temperature superconductivity. Here, we elucidate the structural and
charge distribution in NdNiO$_{2}$ thin films prepared with and without capping
layers, and characterized by the absence and presence of CO. Our
microstructural and spectroscopic analysis was done by scanning transmission
electron microscopy-electron energy loss spectroscopy (STEM-EELS) and hard
x-ray photoemission spectroscopy (HAXPES). Capped samples show Ni$^{1+}$, with
an out-of-plane (o-o-p) lattice parameter of around 3.30 angstroms indicating
good stabilization of the infinite-layer structure. Bulk-sensitive HAXPES on
Ni-2p shows weak satellite feature indicating large charge-transfer energy. The
uncapped samples evidence an increase of the o-o-p parameter up to 3.65
angstroms on the thin-film top, and spectroscopies show signatures of higher
valence in this region (towards Ni$^{2+}$). Here, 4D-STEM demonstrates (3,0,3)
oriented stripes which emerge from partially occupied apical oxygen. Those
stripes form quasi-2D coherent domains viewed as rods in the reciprocal space
with $\Delta\text{q}_{z} \approx 0.24$ r.l.u. extension located at Q = ($\pm
\frac{1}{3},0,\pm \frac{1}{3}$) r.l.u. and Q = ($\pm \frac{2}{3},0,\pm
\frac{2}{3}$) r.l.u. The stripes associated with oxygen re-intercalation
concomitant with hole doping suggests a possible link to the previously
reported CO in infinite-layer nickelate thin films.
