RSI react-spreadsheet-import ⚡️

GitHub Workflow Status GitHub npm


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

  • 📥 Uploader
  • ⚙️ Parser
  • 📊 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 hooks after each step:

  • uploadStepHook - runs only once after uploading the file.
  • selectHeaderStepHook - runs only once after selecting the header row in spreadsheet.
  • matchColumnsStepHook - runs only once after column matching. Operations on data that are expensive should be done here.

The last step - validation step has 2 unique hooks that run only in that step with different performance tradeoffs:

  • 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
  }}
/>

Initial state

In rare case when you need to skip the beginning of the flow, you can start the flow from any of the steps.

  • initialStepState - initial state of component that will be rendered on load.
  initialStepState?: StepState
  
  type StepState =
    | {
        type: StepType.upload
      }
    | {
        type: StepType.selectSheet
        workbook: XLSX.WorkBook
      }
    | {
        type: StepType.selectHeader
        data: RawData[]
      }
    | {
        type: StepType.matchColumns
        data: RawData[]
        headerValues: RawData
      }
    | {
        type: StepType.validateData
        data: any[]
      }

  type RawData = Array<string | undefined>

  // XLSX.workbook type is native to SheetJS and can be viewed here: https://github.com/SheetJS/sheetjs/blob/83ddb4c1203f6bac052d8c1608b32fead02ea32f/types/index.d.ts#L269

Example:

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

<ReactSpreadsheetImport
  initialStepState={{
    type: StepType.matchColumns,
    data: [
      ["Josh", "2"],
      ["Charlie", "3"],
      ["Lena", "50"],
    ],
    headerValues: ["name", "age"],
  }}
/>

Dates and time

Excel stores dates and times as numbers - offsets from an epoch. When reading xlsx files SheetJS provides date formatting helpers. Default date import format is yyyy-mm-dd. Date parsing with SheetJS sometimes yields unexpected results, therefore thorough date validations are recommended.

  • dateFormat - sets SheetJS dateNF option. Can be used to format dates when importing sheet data.
  • parseRaw - sets SheetJS raw option. If true, date formatting will be applied to XLSX date fields only. Default is true

Common date-time formats can be viewed here.

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)

You can see default theme we use here. Your override should match this object's structure.

There are 3 ways you can style the component:

1.) Change theme colors globally

    <ReactSpreadsheetImport
        {...mockRsiValues}
        isOpen={isOpen}
        onClose={onClose}
        onSubmit={setData}
        customTheme={{
          colors: {
            background: 'white',
            ...
            rsi: {
              // your brand colors should go here
              50: '...'
              ...
              500: 'teal',
              ...
              900: "...",
            },
          },
        }}
      />

2.) Change all components of the same type, like all Buttons, at the same time

<ReactSpreadsheetImport
  {...mockRsiValues}
  isOpen={isOpen}
  onClose={onClose}
  onSubmit={setData}
  customTheme={{
    components: {
      Button: {
        baseStyle: {
          borderRadius: "none",
        },
        defaultProps: {
          colorScheme: "yellow",
        },
      },
    },
  }}
/>

3.) Change components specifically in each Step.

    <ReactSpreadsheetImport
        {...mockRsiValues}
        isOpen={isOpen}
        onClose={onClose}
        onSubmit={setData}
        customTheme={{
          components: {
            UploadStep: {
              baseStyle: {
                dropzoneButton: {
                  bg: "red",
                },
              },
            },
          },
        }}
      />

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