This blog presented multiple methods to convert CSV to JSON string using numerous examples. Similarly, the “ csv.DictReader()” function of the CSV module is used along with the “ json.dumps()” function to convert the CSV to JSON string. The “ df.to_json()” function is used along with the “ pd.read_csv()” function to read and convert CSV to JSON string. The “df.to_json()” function of the Pandas module and the CSV module, along with the JSON module, is used to convert the CSV to JSON string in Python. The CSV file has been converted into a JSON string. The “json.dumps()” function accepts the reader data and indent value as an argument and writes it into a JSON file as JSON string.The “with open()” function is utilized to open the file in “w” writing mode.The “for loop” iterates over the rows of the reader object and assigns each row to the variable named “rows”.The “csv.DictReader()” is used to read each row of the CSV file as a dictionary with column names as keys. import csv import json csvfile open ('file.csv', 'r') jsonfile open ('file.json', 'w') fieldnames ('FirstName','LastName','IDNumber','Message') reader csv.DictReader ( csvfile, fieldnames) for row in reader: json.dump (row, jsonfile) jsonfile.The “with open()” function is used to open the CSV file in “r” reading mode.The empty dictionary is assigned to a variable named “data”.The “csv” and “json” modules are imported at the start using the “import” keyword.Terse Mode and Json Lines Mode - one object per line with no commas separating objects.Optionally do not write out field : value if field value is empty.Optionally output null instead of "" for empty fields.Convert value of NULL in CSV to be null in JSON.Sort CSV data in ascending or descending order before converting to JSON.Create nested JSON output by using / in the column headings of CSV.Īrrays are created from duplicate column names or /0, /1.Filter JSON output by using the query tool.Select the fields to output and also rearrange JSON fields.Choose to limit the number of records processed.Choose your attribute names to be upper or lower case.Automatic detection of numeric values, logical values, and nulls.Generate JSON via Template - Using our template engine, easily customize your JSON output NEW.CSV to JSON Column Array - An array of CSV values where each column of values are in an array.Or a structure with column names and data as an array
]ĬSV to JSON Array - An array of CSV values where the CSV values are in an array, Of the remaining fields, also known as an hash table or associative array.
