Expand stroke/create outline of multiple SVG

For anyone looking for a solution in 2022:

1. Create a folder on your desktop named "svg-exports" (no quotes).
2. Inside "svg-exports", create two folders named "svgs" and "converted".
3. Place the SVG files you want to convert inside the "svgs" folder. Better to test with a small number of SVGs like 50-100 files.
4. Create a new notepad file and copy/paste the code below. Modify the path for rootFolder to fit your own path. Remember to end the path with a /
5. Save the Notepad file on Desktop as SVG Outliner.jsx
6. Open Illustrator and go to Files > Scripts > Other Scripts. Run the SVG Outliner.jsx
7. Open the Converted folder and watch as the processed files count up.

// Change this to your AI files folder (Be sure to end with a /)

var rootFolder = "/C/Users/YOURNAME/Desktop/svg-exports/";
var srcFolder = "svgs/"
var outputFolder = "converted/"

function getFiles() {
  var path = rootFolder + srcFolder;
  var folder = new Folder(path);
  if (folder.exists) {
    return folder.getFiles("*.svg");
  } else {
    throw("Unable to find folder at " + path);
  }
}

function saveFile(destination, name, document) {
  var folder = new Folder(destination);
  if (!folder.exists) folder.create();
  var destFile = new File(destination + name);
  var options = new ExportOptionsSVG();
  document.exportFile(destFile, ExportType.SVG, options);
}

function main() {
  try {
    var files = getFiles();
    for (var i = 0; i < files.length; i++) {
      // Open each file
      var file = files[i];
      var document = app.open(file);
      document.activate();
      expandFile();
      saveFile(rootFolder + outputFolder, document.name, document);
      document.close();
    }
  } catch(e) {
    alert(e);
  }
}

function expandFile() {
  app.executeMenuCommand("selectall");
  // app.executeMenuCommand("Live Outline Stroke");
  app.executeMenuCommand("OffsetPath v22"); // Outline path
  app.executeMenuCommand("Live Pathfinder Merge"); // Outline path
  app.executeMenuCommand("expandStyle");
}

/*
 * Run script
 */
main();

Whoops, give us a moment ill change to SVG saving

Hellos,

For this you can use the executeMenuCommand to run the expand options like so:

app.executeMenuCommand("selectall");
app.executeMenuCommand ('Live Outline Stroke');
app.executeMenuCommand ('expandStyle');

Full script that will open all SVG files within a folder then save to an output folder within the original folder.

//Change this to your AI files folder (Be sure to end with a /)
var location = "/Path/To/Folder/Containing/SVG/Files/";
function getFiles() {
  var folder = new Folder(location);
  if (folder.exists) {
    return folder.getFiles("*.svg");
  } else {
    alert("Unable to find SVG Files Folder");
  }
}
function openFiles(files) {
  var documents = [];
  for (var i = 0; i < files.length; i++) {
    var file = files;
    documents.push(app.open(file));
  }
  return documents;
}
function saveFile(destination, name, document) {
  var folder = new Folder(destination);
  if (!folder.exists) folder.create();
  var destFile = new File(destination + name);
  document.saveAs(destFile);
}
/*
 * Run script
 */
 openAndExpand();
function openAndExpand() {
  try {
    var files = getFiles();
    if (files.length > 0) {
      //Open Each File
      var documents = openFiles(files);
      if (documents.length > 0) {
        //Expand Each File and Save
        for (var i = 0; i < documents.length; i++) {
          var document = documents;
          document.activate();
          expandFile();
          saveFile(location + "/output/", document.name, document);
        }
        //Close All Documents
        for (var i = 0; i < documents.length; i++) {
            documents.close();
        }
      }
    }
  } catch(e) {
    alert("Error Processing:");
    alert(e);
  }
}
function expandFile() {
  app.executeMenuCommand("selectall");
  app.executeMenuCommand ('Live Outline Stroke');
  app.executeMenuCommand ('expandStyle');
}
