Export and Import Data on Node.js

You can export and import data of DHTMLX Gantt which is built with Node.js.

To try out the functionality, download the demo. To run the demo you need to install the gantt-node package.

To configure export/import for your project, download the api.js file and include its code into the Gantt configuration file. Read the information below for more details.

Exporting data

The export functionality should work the same way as it works in the web version, with some exceptions:

  • Export to Excel needs the timeline to be shown on the page if the tasks are loaded into the gantt. Since the DOM element of the timeline isn't rendered on Node.js at all, export to Excel won't work by itself because the gantt won't be able to implement internal calculations related to the tasks' positioning in the timeline. As a workaround, you need to specify the loaded tasks as a value of the data parameter in the export settings:
data: gantt.serialize().data
  • When configuring export, specify the callback parameter to define the endpoint of the output file, otherwise, the file will be printed to the console.

Importing data

The import functionality needs the additional formData component to be installed:

npm install form-data


Import from MSP and PrimaveraP6 files should work the same way as it works in the web version.

When importing an Excel file, the data of the file will return to Gantt in the JSON format. Since the columns may have arbitrary names in Excel, it is necessary to map the columns of the Excel document to the task's properties of DHTMLX Gantt. For this, you need to develop your own solution.
