There are 2 inputs you might have and you can also convert between them   input  listOfDictionaries -- gt  use  VikashSingh solution  example     quot  quot    quot     The pd DataFrame   needs a listOfDictionaries as input   input  jsonStr -- gt  use  JustinMalinchak solution  example     quot  quot    quot     If you have jsonStr  you need an extra step to listOfDictionaries first  This is obvious as it is generated like  jsonStr   json dumps listOfDictionaries   Thus  switch back from jsonStr to listOfDictionaries first  listOfDictionaries   json loads jsonStr
