Start with the failing step.

Self-help below covers anonymous use. Signed-in support is provided through the feedback form in the Loam dashboard so a request carries the right account context without publishing an email address.

The local CSV will not open

• Confirm the filename ends in .csv and is within 20 MB, 100,000 rows, and 500 columns.
• Check for an unmatched quote and export as UTF-8 CSV from the source application.

The temporary upload stopped

• Keep the tab open and choose Resume after a paused upload.
• If the page was reloaded, the in-memory token is gone; start a new temporary workspace.
• If the 24-hour lease expired, start again. Activity does not extend it.
• Add a filter or narrower projection in governed Loam if a query would exceed 10,000 rows or 16 MiB.

The output is unexpected

• Remove steps from the end until the preview matches expectations.
• Check the selected columns and operation order.
• Remember that fuzzy suggestions never merge records automatically.

Do not upload data you lack authority to process or include private file contents, credentials, or sensitive records in a support request.
