Batch operations can be slow with large worksheets

Use external loops-not worksheet loops-for performance

Minimize screen updates

Preload data to reduce I/O overhead

Macros can access the file system-manage permissions carefully

Avoid executing macros from untrusted sources

Sandbox execution is limited

No internet access from macros unless explicitly scripted

Scripts run with user-level privileges

Log execution time per worksheet

Track input/output history

Monitor error rates

Use batch run summaries

Track calculation consistency

Use meaningful variable names

Apply logging for debugging

Validate user inputs

Break scripts into smaller components

Keep worksheet structures consistent
