+## Replace papaparse with a lighter library
+
+React-admin used to bundle the `papaparse` library for converting JSON to CSV. But 90% of the `papaparse` code is used to convert CSV to JSON. 
+
+We decided to replace it by a lighter library: [jsonexport](https://github.com/kauegimenes/jsonexport).
+
+If you had custom exporter on `List` components, here's how to migrate:
+
+```diff
+-import { unparse as convertToCSV } from 'papaparse/papaparse.min';
++import jsonExport from 'jsonexport/dist';
+
+-const csv = convertToCSV({
+-    data: postsForExport,
+-    fields: ['id', 'title', 'author_name', 'body']
+-});
+-downloadCSV(csv, 'posts');
++jsonExport(postsForExport, {
++    headers: ['id', 'title', 'author_name', 'body']
++}, (err, csv) => {
++    downloadCSV(csv, 'posts');
++});
+```

 The columns of the CSV file match all the fields of the records in the `dataProvider` response. That means that the export doesn't take into account the selection and ordering of fields in your `<List>` via `Field` components. If you want to customize the result, pass a custom `exporter` function to the `<List>`. This function will receive the data from the `dataProvider` (after step 1), and replace steps 2-3 (i.e. it's in charge of transforming, converting, and downloading the file).
 
-**Tip**: For CSV conversion, you can import [Papaparse](https://www.papaparse.com/), a CSV parser and stringifier which is already a react-admin dependency. And for CSV download, take advantage of react-admin's `downloadCSV` function.
