Why Does `json.loads` Throw a `ValueError: Extra Data` When Parsing a JSON File?

Python json.loads Shows ValueError: Extra Data

When using json.loads to parse a JSON file, you may encounter a ValueError: Extra data error. This indicates that there is additional data in the JSON file beyond what is expected by the decoder.

To resolve this issue, you can try the following steps:

Load JSON Data Line by Line

Instead of loading the entire JSON file at once, iterate through the file and load each line as JSON:

with open('new.json') as infile:
    tweets = []
    for line in infile:
        tweets.append(json.loads(line))

This approach avoids storing intermediate Python objects and ensures that each line is parsed as a valid JSON object.

Example Data

You provided an example data snippet from the new.json file. Examining the snippet, it appears that the data is contained in a single line. Therefore, you can directly load the data into a JSON object using:

import json

with open('new.json') as infile:
    data = json.load(infile)

Ensure that the file contains only valid JSON data and no additional characters that could trigger the ValueError: Extra data.
