Hi I am getting a string like below when parsing a CSV file using csvtojson npm module .

"{"baselineWifiStrength":"10Mbps","userWifiStrength":"3Mbps"}"

Code to read from csv

const csvData = req.files.csvfile.data.toString('utf8');

 csvtojson().fromString(csvData).then(async (json) =>{

        const queriesNew = json.map(async (l) => {
        JSON.parse(l.structure); // crashes here 
})


})

How can I convert the above to a valid JSON Object . I am getting parse error If I do JSON.parse(). Is there a way to solve this ?

Basically I want to convert the "{"baselineWifiStrength":"10Mbps","userWifiStrength":"3Mbps"}" to valid JSON

Parses fine here – CertainPerformance Mar 31 '20 at 10:30
@CertainPerformance sorry where ? – naveen Mar 31 '20 at 10:32
On my end, `JSON.parse('{"baselineWifiStrength":"10Mbps","userWifiStrength":"3Mbps"}')` – CertainPerformance Mar 31 '20 at 10:33
there is no "JSON Object" due to JSON is always a string. JSON strings can be parsed and converted to objects using `JSON.parse` – messerbill Mar 31 '20 at 10:35
@CertainPerformance your works because you are trying out '{"baselineWifiStrength":"10Mbps","userWifiStrength":"3Mbps"}' but for me its "{"baselineWifiStrength":"10Mbps","userWifiStrength":"3Mbps"}" – naveen Mar 31 '20 at 10:37

So you have double quotes as the first and last character of the string? – Aplet123 Mar 31 '20 at 10:42
@naveen Those two are exactly the same, just two different quotation marks, both of which can be used for strings. If your string does contain quotes at the very start and end, you may want to strip those. – Celsiuss Mar 31 '20 at 10:43
