ENH: Add nrows parameter to pd.read_json · Issue #33916 · pandas-dev/pandas (original) (raw)

Is your feature request related to a problem?

Let's say I have a huge jsonlines file and I want to read only the first n lines of the file.

Describe the solution you'd like

This problem could be fixed by adding nrows parameter in method pd.read_json. This parameter should be applicable if and only if lines=True

API breaking implications

Simply add and implement nrows parameter in pd.read_json (like pd.read_csv).

Additional context

How this enhancement could work:

import pandas as pd

df = pd.read_json('/path/to/file.jsonlines', lines=True, nrows=1000)
