“The Wells Fargo file is rejected by my software”
Wells Fargo exports are usually well-formed, which makes their failures confusing: the file looks fine, and the error blames the format. The causes are almost always the download options rather than the data itself.
Symptoms
The file is refused with a generic invalid-format message Fewer transactions arrive than the statement shows Only some accounts export successfully
What actually causes it
The download range exceeded what is available
Requesting more history than the bank retains returns a shorter file without any warning that the rest was dropped, which reads as a truncated or broken export rather than a limit.
A format chosen for a different program
The export menu lists several options whose names refer to software products. The Quicken and QuickBooks variants carry different identifiers, and the spreadsheet option is plain CSV with no account information at all.
Session timeout during generation
Larger exports take time to build, and a session that expires mid-generation yields a truncated file or an error page saved under the expected filename.
How to fix it
- Drop the file into the fixer below: it reports the transaction count and whether the structure is complete, which separates "short range" from "truncated download" immediately.
- If it reports truncation, download again in smaller date ranges rather than one long one.
- Confirm you picked the export variant that matches your software, not the spreadsheet option, when the error mentions accounts or identifiers.
- Compare the reported count against your statement so a short file is caught before it reaches your books.
