Utilizing Scripts for Bulk Imports

When it comes to managing your game data in Foundry Virtual Tabletop (VTT), efficiency is key. One of the most effective ways to enhance your workflow is by automating the import process of .JSON files. This not only saves time but also reduces the potential for human error during manual imports. In this section, we will delve into how you can utilize scripts for bulk importing .JSON files into Foundry VTT.

Using scripts for bulk imports allows you to handle multiple .JSON files simultaneously, streamlining the process significantly. With the right script, you can:

Save Time: Instead of importing files one by one, a script can automate the entire process in a matter of seconds.
Reduce Errors: Automated scripts minimize the chances of errors that can occur during manual data entry.
Enhance Consistency: Scripts ensure that the import process is consistent every time, maintaining the integrity of your game data.

To begin automating your import process, you will need to write a script. Here’s a simplified overview of the steps involved:

1. Choose a scripting language: JavaScript is commonly used within Foundry VTT.2. Access the Foundry API: Familiarize yourself with the API documentation to understand how to interact with game data.3. Write the script: Create a function that reads all .JSON files from a specified directory and imports them using the Foundry API.4. Test the script: Run the script in a controlled environment to ensure it works as expected.

Below is a basic example of a JavaScript function that can be used for bulk importing .JSON files:

async function bulkImportJSON() {    const files  await getFilesFromDirectory('path/to/your/json/files');    for (const file of files) {        const data  await fetch(file).then(response > response.json());        await importDataToFoundry(data);    }}

This script assumes you have a function getFilesFromDirectory that retrieves all .JSON files from a specified folder and an importDataToFoundry function that handles the actual import process.
