Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
  • I am using the latest version of Open WebUI.

Installation Method

Other

Open WebUI Version

v0.8.10

Ollama Version (if applicable)

No response

Operating System

windows server 2008

Browser (if applicable)

No response

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

The file should be processed successfully, regardless of the case of internal filenames (e.g., SharedStrings.xml or sharedStrings.xml).

Actual Behavior

When attempting to upload and process a valid .xlsx file via the OpenWebUI API, the system fails with the error:
Copy

"There is no item named 'xl/sharedStrings.xml' in the archive"

However, upon manual inspection of the .xlsx file (which is a ZIP archive), the file xl/SharedStrings.xml does exist, but the first letter of the filename is uppercase (SharedStrings.xml instead of sharedStrings.xml).
This suggests that the file processing logic in OpenWebUI performs a case-sensitive check for the presence of xl/sharedStrings.xml, which fails for files where the filename uses a different case (e.g., SharedStrings.xml). This is problematic because:

The Office Open XML (OOXML) specification does not enforce a specific case for internal filenames in .xlsx files.
Many tools (including Microsoft Excel and LibreOffice) may generate .xlsx files with varying filename cases, leading to false negatives during processing.

Steps to Reproduce

Steps to Reproduce:

Upload test.xlsx file to OpenWebUI chat.
Observe the error: "There is no item named 'xl/sharedStrings.xml' in the archive".
