Info on flags

  • The --projectKey is only required if states have a transitions field containing one or more states that need to be resolved, otherwise it can be omitted. More info in the Examples below
  • The --input flag specifies the path to the states CSV file. If this flag is omitted, the module will attempt to read the data from the standard input.
  • The --output flag specifies where to output/save the parsed states as JSON file. Several notes on this flag:
    • If the file specified already exists, it will be overwritten.
    • If no output path is specified, the parsed states will be written to the standard output. As a result, status reports will be logged to a csv-parser-state.log file in the current directory.
  • The --delimiter flag specifies the delimiter used in the input file. Defaults to ',' if omitted.
  • The --multiValueDelimiter flag specifies the delimiter for multiValue cells in CSV. Note that only the transitions and roles fields if present should contain multiple values. Defaults to ';' if omitted.
  • The --continueOnProblems flag specifies if the module should continue parsing states if it encounters an error. Defaults to false if omitted.
    • If the module should continue on error, all errors are logged to the logging location (see above).
    • If the module should not continue on error, the failing error is written to the stderr, regardless of the output and logging locations


For more direct usage, it is possible to use this module directly:

const fs = require('fs')
const CsvParserState = require('@commercetools/csv-parser-state')

const csvParser = new CsvParserState(configuration, logger)

const inputStream = fs.createReadStream('path-to-input-file.csv')
const outputStream = fs.createWriteStream('path-to-destination.json')

csvParser.parse(inputStream, outputStream)

// Listen for events
  .on('error', (error) => {
    // <- Handle errors here
  .on('finish', () => {
    // <- Do something here

The constructor takes in 2 optional parameters

  • A configuration object containing any/all of the following values:
    • apiConfig (Object): AuthMiddleware options for authentication on the commercetools platform. (only required if states have a transitions field containing one or more states that need to be resolved. See here)
    • csvConfig (Object): A configuration object for describing the CSV file:
      • delimiter (String): Used delimiter in the CSV (Default: ',')
      • multiValueDelimiter (String): Used delimiter in multiValue fields in the CSV (Default: ';')
    • accessToken (String): Access token to be used to authenticate requests to API. Requires scope of [view_orders]
    • continueOnProblems (Boolean): Option if module should continue on errors (Default: false)
  • A logger object having four functions (info, warn, error and debug)

CSV Notes

The CSV transitions in the CSV file should contain the list of state keys that can be transitioned to. This keys should be separated by the supplied multiValueDelimiter. A valid CSV file with valid transitions using the default multiValueDelimiter (;) is given below:



If we want to parse 3 states from CSV to JSON; with the following as input:

James,Flo,some description,eine beschreibung,state-key-1,OrderState,true,Initial
Easter,Oster,some description 4,eine beschreibung 4,state-key-2,ProductState,false,Initial;some-state-key;another-state-key
Ascension,Feiertag,some good description 5,eine gute beschreibung 5,state-key-3,LineItemState,false,

Using the CLI, we could run the following command:

csv-parser-state -p my-project-key -i /path-to-input-file.csv -o /path-to-output.json

And the following would be written to the JSON file

    "name": {
      "en": "James",
      "de": "Flo"
    "description": {
      "en": "some description",
      "de": "eine beschreibung"
    "key": "state-key-1",
    "type": "OrderState",
    "initial": true,
    "transitions": [
        "typeId": "state",
        "id": "<Initial-state-id>"
    "name": {
      "en": "Easter",
      "de": "Oster"
    "description": {
      "en": "some description 4",
      "de": "eine beschreibung 4"
    "key": "state-key-2",
    "type": "ProductState",
    "initial": false,
    "transitions": [
        "typeId": "state",
        "id": "<Initial-state-id>"
        "typeId": "state",
        "id": "<some-state-id>"
        "typeId": "state",
        "id": "<another-state-id>"
    "name": {
      "en": "Ascension",
      "de": "Feiertag"
    "description": {
      "en": "some good description 5",
      "de": "eine gute beschreibung 5"
    "key": "state-key-3",
    "type": "LineItemState",
    "initial": false
