The difference between a CSV and TSV is only the separator used in between the value: CSV uses a comma and TSV uses a tab. Also, a TSV or CSV to JSON conversion function in JavaScript is pretty simple. That is an option, and there are many converters out there, but what about transferring more data over the network? CSV and TSV are always going to be smaller than JSON and I like that, so often times, I actually prefer to load a CSV file into the page and convert it into JSON with JavaScript. You could argue that I should just convert the data into JSON before loading it onto the page, especially since at the end of the day I will need to convert it into a JavaScript object. D3.js supports it out of the box which is awesome but often times I need to convert CSV to JSON without loading D3. Pattern pattern = Pattern.I have been dealing with a lot of CSV and TSV files lately and I am a bit surprised at the lack of support for these formats in jQuery. Mapper.enable(SerializationFeature.INDENT_OUTPUT) Īnd here is the whole programs segment. ObjectMapper mapper = new ObjectMapper() Check for full details on JSON serialization and deserialization. Once the Listis ready, use Jackson’s ObjectMapper to write the JSON. We are going to parse the CSV data and create the POJO (Plain-Old-Java-Object) shown in this definition. When the CSV file to be parsed is simple (there are no quoted fields or commas embedded in fields), you can use a simple pattern matcher to split the CSV fields.

In this method, we use the Java Collection classes to store the parsed data and convert those to JSON.

The second method uses a more complete CSV parser with support for quoted fields and commas embedded within fields. The first method defines a POJO and uses simple string splitting to convert CSV data to a POJO, which, in turn, is serialized to JSON. In this article, we present a couple of methods to parse CSV data and convert it to JSON.
