Charged particle spectra are measured in proton-proton collisions at center-of-mass energies 7000 GeV. The spectra are normalized to all non-single-diffractive (NSD) events using corrections for trigger and selection efficiency, acceptance, and branching ratios. There are transverse-momentum ($p_\perp$) spectra from 0.1 to 2 GeV in bins of pseudorapidity ($\eta$) and the $p_\perp$ spectrum from 0.1 to 6 GeV for $|\eta| < 2.4$. The $\eta$ spectra come from the average of three methods and cover $|\eta| < 2.5$ and are corrected to include all $p_\perp$. The data were corrected according to the SD/DD/ND content of the CMS trigger, as predicted by PYTHIA6. The uncertainties connected with correct or incorrect modelling of diffraction were included in the systematic errors.
