JSONDecodeError on JSON with multiple lines
Hi !

The `json` dataset script does support this format. For example loading a dataset with this format works on my side:
```json
{"key1":11, "key2":12, "key3":13}
{"key1":21, "key2":22, "key3":23}
```

Can you show the full stacktrace please ? Also which version of datasets and pyarrow are you using ?

 Hi Quentin!

I apologize for bothering you. There was some issue with my pyarrow version as far as I understand. I don't remember the exact version I was using as I didn't check it.

I repeated it with `datasets 1.2.1` and `pyarrow  2.0.0` and it worked.

Closing this issue. Again, sorry for the bother.

Thanks,
Gunjan
Hello :),

I have been trying to load data using a JSON file. Based on the [docs](https://huggingface.co/docs/datasets/loading_datasets.html#json-files), the following format is supported:

```json
{"key1":11, "key2":12, "key3":13}
{"key1":21, "key2":22, "key3":23}
```
 But, when I try loading a dataset with the same format, I get a JSONDecodeError : `JSONDecodeError: Extra data: line 2 column 1 (char 7142)`. Now, this is expected when using `json` to load a JSON file. But I was wondering if there are any special arguments to pass when using `load_dataset` as the docs suggest that this format is supported.

When I convert the JSON file to a list of dictionaries format, I get AttributeError: `AttributeError: 'list' object has no attribute 'keys'`. So, I can't convert them to list of dictionaries either.

Please let me know :)

Thanks,
Gunjan
