Upload your first DFMEA

Follow these five steps to go from a raw DFMEA spreadsheet to a structured findings report. The whole process takes under two minutes once your file is ready.

1. 1

   Prepare your file

   Specwarden accepts .xlsx, .xls, and .csv files. Before uploading, confirm your spreadsheet has a header row with column names in the first non-blank row. Merged cells are supported — Specwarden forward-fills them automatically. Remove any summary or cover sheets that do not contain DFMEA data; Specwarden will prompt you to select the correct sheet if more than one is detected.

2. 2

   Go to New Review

   From your dashboard, select New Review. You must be signed in. Free-tier accounts include 3 reviews per month; Pro and Pro Plus include 25 reviews per month, with $3 per additional review thereafter.

3. 3

   Upload your file

   Drag your file onto the upload zone or click Browse to open a file picker. Maximum file size is 10 MB. Files are transmitted directly to the review engine over TLS and are never written to disk or stored on Specwarden servers — the server discards the file as soon as the response is returned.

4. 4

   Confirm column mapping

   Specwarden auto-detects which of your columns correspond to DFMEA fields such as Function, Failure Mode, Severity, and Detection. Columns detected with high confidence are mapped automatically and shown in green. Columns marked Verify are shown in amber — review these and confirm or correct them before proceeding. Required columns that could not be matched are shown in red and must be mapped manually. You can save the mapping as a template to reuse on future uploads with the same column layout.

5. 5

   Review and export

   After you confirm the mapping, Specwarden runs the review. Findings appear in roughly 60 seconds for files up to 200 rows. Free-tier accounts see the first 5 findings; upgrade to a paid plan to see all findings. When review is complete, use the Export button to download a PDF or Word report. You can also enter your email address to have the report sent to your inbox.
