If I had a file whose contents looked like:
{"one": 1}
{"two": 2}
I could simply parse each separate line as a separate JSON object (using JsonCpp). But what if the structure of the file was less convenient like this:
{
"one":1
}
{
"two":2
}
No one has mentioned arrays:
[
{"one": 1},
{"two": 2}
]
Is valid JSON and might do what the OP wants.
You can also use this custom function to parse multiple root elements even if you have complex objects.
static getParsedJson(jsonString) {
const parsedJsonArr = [];
let tempStr = '';
let isObjStartFound = false;
for (let i = 0; i < jsonString.length; i += 1) {
if (isObjStartFound) {
tempStr += jsonString[i];
if (jsonString[i] === '}') {
try {
const obj = JSON.parse(tempStr);
parsedJsonArr.push(obj);
tempStr = '';
isObjStartFound = false;
} catch (err) {
// console.log("not a valid JSON object");
}
}
}
if (!isObjStartFound && jsonString[i] === '{') {
tempStr += jsonString[i];
isObjStartFound = true;
}
}
return parsedJsonArr;
}
