A component used for importing XLS / XLSX / CSV documents built with Chakra UI. Import flow combines:

• 📥 Uploader

• 📊 File preview
• 🧪 UI for column mapping
• ✏ UI for validating and editing data

✨ Demo ✨

Features

• Custom styles - edit Chakra UI theme to match your project's styles 🎨
• Custom validation rules - make sure valid data is being imported, easily spot and correct errors
• Hooks - alter raw data after upload or make adjustments on data changes
• Auto-mapping columns - automatically map most likely value to your template values, e.g. name -> firstName

Getting started

npm i react-spreadsheet-import

Using the component: (it's up to you when the flow is open and what you do on submit with the imported data)

import { ReactSpreadsheetImport } from "react-spreadsheet-import";

<ReactSpreadsheetImport
  isOpen={isOpen}
  onClose={onClose}
  onSubmit={onSubmit}
  fields={fields}
/>

Required Props

  // Determines if modal is visible.
  isOpen: Boolean
  // Called when flow is closed without reaching submit.
  onClose: () => void 
  // Called after user completes the flow. Provides data array, where data keys matches your field keys.
  onSubmit: (data) => void 

Fields

Fields describe what data you are trying to collect.

const fields = [
  {
    // Visible in table header and when matching columns.
    label: "Name",
    // This is the key used for this field when we call onSubmit.
    key: "name",
    // Allows for better automatic column matching. Optional.
    alternateMatches: ["first name", "first"],
    // Used when editing and validating information.
    fieldType: {
      // There are 3 types - "input" / "checkbox" / "select".
      type: "input",
    },
    // Used in the first step to provide an example of what data is expected in this field. Optional.
    example: "Stephanie",
    // Can have multiple validations that are visible in Validation Step table.
    validations: [
      {
        // Can be "required" / "unique" / "regex"
        rule: "required",
        errorMessage: "Name is required",
        // There can be "info" / "warning" / "error" levels. Optional. Default "error".
        level: "error",
      },
    ],
  },
] as const

Optional Props

Hooks

You can transform and validate data with custom hooks. There are 3 hooks that have different performance tradeoffs:

• initialHook - runs only once after column matching. Operations that should run once should be done here.
• tableHook - runs at the start and on any change. Runs on all rows. Very expensive, but can change rows that depend on other rows.
• rowHook - runs at the start and on any row change. Runs only on the rows changed. Fastest, most validations and transformations should be done here.

Example:

<ReactSpreadsheetImport
  rowHook={(data, addError) => {
    // Validation
    if (data.name === "John") {
      addError("name", { message: "No Johns allowed", level: "info" })
    }
    // Transformation
    return { ...data, name: "Not John" }
    // Sorry John
  }}
/>

Other optional props

  // Allows submitting with errors. Default: true
  allowInvalidSubmit?: boolean
  // Translations for each text. See customisation bellow
  translations?: object
  // Theme configuration passed to underlying Chakra-UI. See customisation bellow
  customTheme?: object
  // Specifies maximum number of rows for a single import
  maxRecords?: number
  // Maximum upload filesize (in bytes)
  maxFileSize?: number
  // Automatically map imported headers to specified fields if possible. Default: true
  autoMapHeaders?: boolean
  // Headers matching accuracy: 1 for strict and up for more flexible matching. Default: 2
  autoMapDistance?: number

Customisation

Customising styles (colors, fonts)

Underneath we use Chakra-UI, you can send in a custom theme for us to apply. Read more about themes here

<ReactSpreadsheetImport
  customTheme={yourTheme}
/>

You can see all the changable styles here

Changing text (translations)

You can change any text in the flow:

<ReactSpreadsheetImport
  translations={{
    uploadStep: {
      title: "Upload Employees",
    },
  }}
/>

You can see all the translation keys here
