在JSON中现有的双引号内搜索和替换双引号

Question

I have data that loks like this:

"contributors": null, "truncated": false, "text": "This is "what" we call text", "coordinates": null

Notice the double quotes inside existing double quotes for the "text" node (bad data, I know). The data set is HUGE, so manual clean-up would be out of the question. I'm streaming the data using Node.js, so I can do the replace on a line-by-line basis. Is there any way with JS to escape (or change to single quote) these instances? Any assistance would be appreciated. Thanks

Answer 1

Not with Node.js, since you need a lookbehind assertion to negate valid JSON schema characters ( : and , ).

You could do this though, in something like Python. It won't catch everything though, and you'll probably have to do some manual cleanup:

(?<![:,] )"(?![:,])
