【问题描述】：
我有一个从网络抓取中获得的 DataFrame，如下所示：
data = [{'StrategicResearchPriorities': {'data': [{'strategicAreaId': 0,
'strategicAreaValue': 'Population',
'strategicGoalId': 1,
'strategicGoalValue': 'Social'}]},
'ScienceAndResearchPriorities': {'data': [{'scienceAndResearchPriorityId': 'Health',
'scienceAndResearchPriorityValue': 'Health',
'practicalResearchChallengeId': 'XXX.',
'practicalResearchChallengeValue': 'YYY'}]},
'IndustrialTransformationPriorities': None,
'FieldsOfResearch': '{"data":[{"guid":1557,"value":"200102 - Communication Technology and Digital Media Studies","code":200102,"percentage":"45"},{"guid":1499,"value":"180119 - Law and Society","code":180119,"percentage":"30"},{"guid":1381,"value":"160104 - Social and Cultural Anthropology","code":160104,"percentage":"15"},{"guid":1444,"value":"160808 - Sociology and Social Studies of Science and Technology","code":160808,"percentage":"10"}]}',

'PersonOrdinal': 3},
],
'OrganisationParticipantSummary': '{"data":[{"id":11111,"guid":"af4","name":"Institute","number":1,"roleName":"Administering Organisation","roleId":1,"inKind":true},{"id":22222,"guid":"af6","name":"University","number":2,"roleName":"Other","roleId":3,"inKind":true}]}',

{'StrategicResearchPriorities': {'data': [{'strategicAreaId': 4,
'strategicAreaValue': 'Productivity',
'strategicGoalId': 11,
'strategicGoalValue': 'Economy'}]},
'ScienceAndResearchPriorities': {'data': [{'scienceAndResearchPriorityId': 'Manufacturing',
'scienceAndResearchPriorityValue': 'Manufacturing',
'practicalResearchChallengeId': 'Technologies.',
'practicalResearchChallengeValue': 'Modern technologies.'}]},

'Title': 'A and B and C',

'ChiefInvestigators': [{'FamilyName': 'Surname3',
'FirstName': 'Name3',
'SecondName': None,
'Title': 'Dr',
'PersonOrdinal': 1},
{'FamilyName': 'Surname4',
'FirstName': 'Name4',
'SecondName': 'SecondName4',
'Title': 'Prof',
'PersonOrdinal': 15}],
'OrganisationParticipantSummary': '{"data":[{"id":10002,"guid":"ab3","name":"University","number":1,"roleName":"Owner","roleId":1,"inKind":true},{"id":50000,"guid":"2a7","name":"University2","number":2,"roleName":"Other","roleId":3,"inKind":true}]}',

20,
10],
'UnnamedAwardSummary': {}},
]
我想将所有不同的单元格解压成一个大数据框。我试过了
json_normalize(data)
但单元格像字符串一样被读取。问题是诸如“StrategicResearchPriorities”之类的字段在（“数据”）中有另一个列表，无法访问它。
PS：很抱歉，数组很长，但我认为最好展示所有这些。它实际上已经被修剪了很多。
