How to Create list of GCP Instance / service account across all projects

Below code to list all instances across GCP Projects

PROJECTS=$(gcloud projects list --format="value(projectId)")

for PROJECT in ${PROJECTS}
do
  echo "Project: ${PROJECT}"
  # Extracts ACCOUNT_ID, EMAIL (==ACCOUNT_ID@...), DISABLED
  #ROBOTS=$(\
  #gcloud compute instances list --project=${PROJECT} --format="csv(name,disks[].guestOsFeatures[0].type[],networkInterfaces.networkIP)"
  gcloud compute instances list --project=${PROJECT}  --format="csv(name,disks.licenses.scope(licenses),networkInterfaces.networkIP,selfLink.scope(projects),status)"

done

The below code is to list all service account in GCP across all Projects

for PROJECT in ${PROJECTS}
do
  echo "Project: ${PROJECT}"
  # Extracts ACCOUNT_ID, EMAIL (==ACCOUNT_ID@...), DISABLED
  ROBOTS=$(\
    gcloud iam service-accounts list \
    --project=${PROJECT} \
    --format="csv[no-heading](displayName.encode(\"base64\"),email,email.split(\"@\").slice(0),disabled)")
  for ROBOT in ${ROBOTS}
  do
    # Parse results
    IFS=, read ENCODED_NAME EMAIL ACCOUNT_ID DISABLED <<< ${ROBOT}
    NAME=$(echo -e ${ENCODED_NAME} | base64 --decode)
    echo "  Service Account: ${NAME}"
    echo "    Disabled: ${DISABLED}"
    echo "    Email: ${EMAIL}"
    # Keys
    # KEYS=$(\
    #    gcloud iam service-accounts keys list \
    #    --iam-account=${EMAIL} \
    #    --project=${PROJECT} \
    #    --format="value(name.scope(keys))")
    #for KEY in ${KEYS}
    #do
    #  echo "    Key: ${KEY}"
    #done
 done
done
