There are multiple reasons due to which your statement gets failed after processing. You can simply find out the reason and accordingly resolve and reupload.
When you upload the bank statement in Suvit, the system extracts it into a tabular format. However, if the document shows the stage as "Failed," it can be due to various reasons such as an unsupported format, password-protected file, etc.
After the reason is identified, you can proceed to resolve it.
