Open-source CSV and XLS/XLSX file importer for React and JavaScript
How It Works
- Embed the CSV Importer in your app with the React or JavaScript SDK
- Define the columns your users can import (via the
templateparameter) - Your users import their files in your app
- Retrieve the imported data from the
onCompleteevent
Get Started
1. Install SDK
Use NPM or Yarn to install the SDK for React or JavaScript.
NPM
npm install csv-import-react
# or
npm install csv-import-jsYarn
yarn add csv-import-react
# or
yarn add csv-import-js2. Add the importer to your application
Using React
import { CSVImporter } from "csv-import-react";
import { useState } from "react";
function MyComponent() {
const [isOpen, setIsOpen] = useState(false);
return (
<>
<button onClick={() => setIsOpen(true)}>Open CSV Importer</button>
<CSVImporter
modalIsOpen={isOpen}
modalOnCloseTriggered={() => setIsOpen(false)}
darkMode={true}
onComplete={(data) => console.log(data)}
template={{
columns: [
{
name: "First Name",
key: "first_name",
required: true,
description: "The first name of the user",
suggested_mappings: ["First", "Name"],
},
{
name: "Age",
data_type: "number",
},
],
}}
/>
</>
);
}Using JavaScript
<head>
<script src="https://unpkg.com/csv-import-js@latest/index.js"></script>
</head>
<body>
<button id="uploadButton">Open CSV Importer</button>
<div id="app"></div>
<script>
const importer = CSVImporter.createCSVImporter({
domElement: document.getElementById("app"),
modalOnCloseTriggered: () => importer?.closeModal(),
onComplete: (data) => console.log(data),
darkMode: true,
template: {
columns: [
{
name: "First Name",
key: "first_name",
required: true,
description: "The first name of the user",
suggested_mappings: ["First", "Name"],
},
{
name: "Age",
data_type: "number",
},
],
},
});
const uploadButton = document.getElementById("uploadButton");
uploadButton.addEventListener("click", () => {
importer?.showModal();
});
</script>
</body>SDK Reference
isModal (boolean, default: true)
When set to true (default value), the importer will behave as a modal with its open state controlled by modalIsOpen. When set to false, the importer will be embedded directly in your page.
modalIsOpen (boolean, default: false)
Only used when isModal is true: Controls the importer modal being open or closed.
React SDK Only: For the JavaScript SDK, use .showModal() and .closeModal() to operate the modal.
modalOnCloseTriggered (function)
Only used when isModal is true: A function called when the user clicks the close button or clicks outside of (when used with modalCloseOnOutsideClick) the importer. useState can be used to control the importer modal opening and closing.
const [isOpen, setIsOpen] = useState(false);<button onClick={() => setIsOpen(true)}>Open CSV Importer</button>
<CSVImporter
modalIsOpen={isOpen}
modalOnCloseTriggered={() => setIsOpen(false)}
...
/>modalCloseOnOutsideClick (boolean, default: false)
Only used when isModal is true: Clicking outside the modal will call the modalOnCloseTriggered function.
template (object)
Configure the columns used for the import.
template={{
columns: [
{
name: "First Name",
key: "first_name",
required: true,
description: "The first name of the user",
suggested_mappings: ["First", "Name"],
},
{
name: "Age",
data_type: "number",
},
],
}}onComplete (function)
Callback function that fires when a user completes an import. It returns data, an object that contains the row data, column definitions, and other information about the import.
onComplete={(data) => console.log(data)}Example data:
{
"num_rows": 2,
"num_columns": 3,
"columns": [
{
"key": "age",
"name": "Age"
},
{
"key": "email",
"name": "Email"
},
{
"key": "first_name",
"name": "First Name"
}
],
"rows": [
{
"index": 0,
"values": {
"age": 23,
"email": "[email protected]",
"first_name": "Maria"
}
},
{
"index": 1,
"values": {
"age": 32,
"email": "[email protected]",
"first_name": "Robert"
}
}
]
}darkMode (boolean, default: false)
Toggle between dark mode (true) and light mode (false).
primaryColor (string)
Specifies the primary color for the importer in hex format. Use customStyles to customize the UI in more detail.
primaryColor="#7A5EF8"customStyles (object)
Apply custom styles to the importer with an object containing CSS properties and values. Note that custom style properties will override primaryColor and any default styles from darkMode.
Available options:
customStyles={{
"font-family": "cursive",
"font-size": "15px",
"base-spacing": "2rem",
"border-radius": "8px",
"color-primary": "salmon",

"color-secondary-hover": "crimson",
"color-tertiary": "indianRed",
"color-tertiary-hover": "crimson",
"color-border": "lightCoral",
"color-text": "brown",
"color-text-soft": "rgba(165, 42, 42, .5)",
"color-text-on-primary": "#fff",
