1175744654 I_kwDOCGYnMM5GFHCO 417 insert fails on JSONL with whitespace 9954 closed 0     3 2022-03-21T17:58:14Z 2022-03-25T21:19:06Z 2022-03-25T21:17:13Z NONE  

Any JSON that is newline-delimited and has whitespace (newlines) between the start of a JSON object and an attribute fails due to a parse error.

e.g. given the valid JSONL:

{ "attribute": "value" } { "attribute": "value2" }

I would expect that sqlite-utils insert --nl my.db mytable file.jsonl would properly import the data into mytable. However, the following error is thrown instead:

json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 2 column 1 (char 2)

It makes sense that since the file is intended to be newline separated, the thing being parsed is "{" (which obviously fails), however the default newline-separated output of jq isn't compact. Using jq -c avoids this problem, but the fix is unintuitive and undocumented.

Proposed solutions: 1. Default to a "loose" newline-separated parse; this could be implemented internally as [the equivalent of] a jq -c filter ahead of the insert step. 2. Catch the JSONDecodeError (or pre-empt it in the case of a record === "{\n") and give the user a "it looks like your json isn't actually newline-delimited; try running it through jq -c instead" error message.

It might just have been too early in the morning when I was playing with this, but running pipes of data through sqlite-utils without the 'knack' of it led to some false starts.
