Should You Use the OSHA Web Form or a CSV Upload?
Use the web form when the filing is small and simple. Use CSV when the file is repeatable, multi-establishment, or case-data heavy.
Who this is for
Filers deciding whether CSV cleanup is worth the effort.
Use web forms for small filings
OSHA notes that web forms can be easier for a small number of establishments.
Use CSV when manual entry becomes risky
CSV upload is useful when there are many locations, many case rows, repeat annual work, or consultant workflows.
Validate the CSV before you commit
CSV saves time only when the file is clean. Run validation before upload to avoid a loop of portal rejections.
