Inflation in France was confirmed at 4.1% year-on-year in December, while November consumer spending unexpectedly rose, France's statistics agency INSEE said.
In the agency's final reading, energy prices accelerated slightly more than initially forecast, up by 5.7% year-on-year in December, compared with a preliminary figure of 5.6%.
Services rose by 3.1%, INSEE confirmed.
Food prices continued going up, but once again at a slower pace, rising by 7.2% from 7.7% in the previous month, the agency added.
This marked the ninth month in a row when food price inflation slowed, INSEE said.
France's government hopes this month's annual price negotiations between retailers and food producers will lead to lower prices for consumers, even as some companies engage in a pricing tug-of-war.
French consumer spending, meanwhile, came in higher than expected, rising by 0.7% in November from the previous month, while economists polled by Reuters had forecast a decline of 0.1%.
"This increase is explained by a rebound in energy consumption... and by a further increase in the consumption of manufactured goods," INSEE said in a statement, adding food consumption was stable.
