const selection = figma.currentPage.selection;

selection.forEach(node => {
  // Get current name
  const srcName = node.name;

  // Split by slash e.g. Questionnaire, Age
  const splitName = srcName.split('/');

  const newName = splitName.map(name => {
  // Remove start/end space, and to lowercase
    return name.trim().toLowerCase();
  })

  // Assign new name
  node.name = newName.join('/')
})
