In my csv file, the "ESTABLİSHMENT DATE"
column is delimited by the slashes like this: 01/22/2012
.
I am converting the csv format into the JSON format, which needs to be done with pandas, but the "ESTABLİSHMENT DATE"
column isn't correctly translated to JSON.
df = pd.read_csv(my_csv)
df.to_json("some_path", orient="records")
I don't understand why it awkwardly adds the backward slashes.
"ESTABLİSHMENT DATE":"01\/22\/2012",
However, I need to write the result to a file as the following:
"ESTABLİSHMENT DATE":"01/22/2012",
json
library to solve the issue.
01/22/2012
, the /
will be escaped with \
.'date'
column to a correct datetime dtype
, and then using .to_json
.
2012-01-22
is the correct datetime format, but .to_json
will convert that to 1327190400000
. After using pd.to_datetime
to set the correct format as %Y-%m-%d
, the type must be set to a string
.import pandas as pd
# test dataframe
df = pd.DataFrame({'date': ['01/22/2012']})
# display(df)
date
0 01/22/2012
# to JSON
print(df.to_json(orient='records'))
[out]: [{"date":"01\/22\/2012"}]
# set the date column to a proper datetime
df.date = pd.to_datetime(df.date, format='%m/%d/%Y')
# display(df)
date
0 2012-01-22
# to JSON
print(df.to_json(orient='records'))
[out]: [{"date":1327190400000}]
# set the date column type to string
df.date = df.date.astype(str)
# to JSON
print(df.to_json(orient='records'))
[out]: [{"date":"2012-01-22"}]
# as a single line of code
df.date = pd.to_datetime(df.date, format='%m/%d/%Y').astype(str)
