how to read json data excel file in python

Question

I have excel file in which json data column is present and I want to read each and every value of that column in python than how can I do that? data.xlsx

Answer 1

from ast import literal_eval

import pandas as pd


df_raw = pd.read_excel("data.xlsx")
data_raw = df_raw.loc[:, "data"]

data_raw = data_raw.apply(literal_eval)
data_raw = data_raw.tolist()
df = pd.DataFrame(data_raw)

Basically, I use literal_eval to convert all the JSON strings in the "data" column to Python dicts, then I convert the list of Python dicts to a DataFrame.

Let me know if it works for you!

You can also use the loads function from the json package instead of literal_eval : json.loads is a bit more specific for the JSON format, whereas literal_eval is better if you have a generic dictionary or other Python data structures stored in the Excel file.

Answer 2

import json
import pandas as pd

df = pd.read_excel("data.xlsx")

# Convert strings to dictionaries
df["data"] = df["data"].apply(json.loads)

# Explode dictionaries column into multiple columns
df2 = pd.DataFrame(df["data"].tolist())

# Join ID column with data columns
df = df[["id"]].join(df2)

print(df)
# Output:
#    id name languages
# 0   1  Bob   English
# 1   2  Bob   English
