Rather than manually downloading and re-uploading data, use integrated platforms that handle the XLS-to-IDS transition:
Large VBA macros can trigger security flags and slow down the download. If the goal is data transfer, use a clean .xlsx format instead of .xlsm .
Replace the end of your sharing URL (the /edit?usp=sharing part) with /export?format=xlsx . This forces the browser to download the file directly as an Excel document, skipping the web interface.
Ensure that columns containing Client IDs or Unique Identifiers are specifically included in your export settings. Some platforms, like KoboToolbox , require you to enable "Advanced Export Settings" to include these hidden columns. Safety and Security Considerations
