The Scenario
Your data team needs to feed fifteen CSV files into Manus as context for an upcoming batch of research tasks. The files are ready. The problem is that Manus expects you to register each file through the API first — creating a file record and getting back a presigned S3 URL — before you can actually upload the file contents. The file names and MIME types are already in an Excel workbook: column A has the names, column B has the content types.
You're not a developer. "Presigned URL" is a phrase you've seen but never had to act on.
The bad version:
- Find the Manus file upload API documentation, figure out the request format, write or borrow a script, run it against row one, copy the returned file ID into column C and the upload URL into column D, run it against row two.
- Discover on row seven that the MIME type in column B has a typo and the request is returning 400 errors — go back, fix the workbook, restart from row seven.
- Spend two hours on credential management and request debugging to register fifteen files.
The files need to be attached to tasks that kick off tomorrow morning. The data team shouldn't have to learn REST APIs to make that happen.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the file names and MIME types from the workbook, registers each file with Manus, and writes the returned file IDs and upload URLs back into adjacent columns.
Register Manus file uploads for all 15 rows in this Excel workbook — filename in column A, content type in column B — and capture file IDs in column C
What You Get
- A Manus file record created for each row.
- The file ID written into column C for every successful registration.
- The presigned upload URL written into column D — ready to use for the actual file upload step.
- Failed rows flagged in column C with the error detail instead of a blank.
What If the Data Is Not Quite Ready
Some MIME types in column B are incorrect and I want to normalize them
For each row in this workbook, register a Manus file record using the filename from column A — if the MIME type in column B is blank, default to 'text/csv' — then write the file ID into column C and the upload URL into column D
I only want to register files that haven't been registered yet (column C is blank)
For each row where column C is blank, create a Manus file record using the filename in column A and the MIME type in column B, then write the file ID into column C and the upload URL into column D
The filenames in column A have the folder path prepended — I want just the filename
Register Manus file records for each row — strip any folder path from column A and use only the filename portion as the file name, use column B as the MIME type, write file ID to column C and upload URL to column D
Register the files, then validate that every upload URL is non-empty
Create Manus file records for all 15 rows using column A and column B, write file IDs into column C and upload URLs into column D, then add a column E that marks 'ok' if column D is non-empty or 'missing-url' if it's blank
Catching the missing-URL case in the same pass means you find the failures before the upload step, not during it.
