CSV to JSON

What is CSV to JSON

Because JSON files might contain far more sophisticated structures than CSV files, converting them directly is not always practical.

How to convert CSV to JSON

JSON to CSV Converter transforms the structured content of a JSON file into a table representation.

• Step 1 : Enter or paste CSV text in the first field. In some cases, you can also upload an CSV file.
• Step 2 : Click on the convert button and check the result. If the source is correct, it will then perform the CSV into JSON convertion.
• Step 3: You can copy the resulting JSON, or if you prefer, you can download it as a JSON file.

Why CSV to JSON Converter?

Because it is a reasonably basic format supported by practically all spreadsheet programs and databases, CSV is a prevalent standard for data storage.
When it comes to saving data in JSON format, though, things get complicated.
JSON requires data to be organized into a structure or schema, which is incompatible with the structure of a CSV file.
The CSV to JSON Converter program is used to convert CSV files to JSON format.

What is CSV?

CSV (Comma Separated Value) files are tabular data files containing several rows and columns.
An Excel spreadsheet is an example of a CSV file. These files have the.csv extension, such as coderstool.csv. Every row in this sample file represents a dataset record, and each column represents a unique feature variable.

What is JSON

JSON (JavaScript Object Notation); also ECMA-404, JSON Data Interchange Format

JSON is a lightweight, text-based, language-independent data interchange format. It was derived from the Javascript/ECMAScript programming language, but is programming language independent. JSON is considered as a lightweight alternative to XML, as in JSON: The Fat-Free Alternative to XML, a 2006 presentation by JSON's developer, Douglas Crockford. JSON defines a small set of structuring rules for the portable representation of structured data. JSON provides simple notation for expressing objects, collections of name/value pairs, and for arrays, ordered lists of values. By nesting these two basic structures, trees and other complex data structures can be represented.

JSON syntax uses braces (curly brackets: {} ), square brackets ( [] ), colons, and commas to arrange values that are strings (sequences of characters in double quotes) or numbers (expressed as sequences of digits) into the two basic structures.

An object is an unordered set of name/value pairs. An object begins with { (left brace) and ends with } (right brace). Each name is followed by : (colon) and the name/value pairs are separated by , (comma). An array is an ordered collection of values. An array begins with [ (left bracket) and ends with ] (right bracket). Values are separated by , (comma). A value can be a string in double quotes, or a number, or true or false or null, or an object or an array. These structures can be nested.

To convert CSV to JSON in Python, follow these steps.

1. Initialize a Python List.
2. Read the lines of CSV file using csv.DictReader() function.
3. Convert each line into a dictionary. Add the dictionary to the Python List created in step 1.
4. Convert the Python List to JSON String using json.dumps().
5. You may write the JSON String to a JSON file.
