The code returns the following error:
Error processing file undefined: file.arrayBuffer is not a function
at processFiles (/app/components/file-upload)
Revise the code to address the error.

I need to fix the file processing error. The issue is with how we're handling the File objects in the drag and drop functionality. Let me update the file upload component to properly handle the file processing.
The error was occurring because the file objects weren't properly maintaining their arrayBuffer method after being processed through the state management. I've fixed this by:
new File([file], file.name, { type: file.type }) to ensure all File API methods are available.The fix ensures that the arrayBuffer() method is available when we try to read the Excel files, which should resolve the error you encountered.

Web App to Organize Purchasing Data from Excel Sheets
⚠️ Currently: Upload and Item Collection Functions Are Not Working
Hi,
This is an update and issue report for the app I'm trying to build.
📌 Purpose:
The app should allow uploading Excel files that contain item purchase requests (in multiple sheets), and then automatically collect and consolidate all the items into one clean list for the purchasing department.
✅ Core Features (as planned):
File Upload:
Upload one or more Excel files.
Each file may contain multiple sheets, each listing items and quantities.
Item Extraction & Consolidation:
Automatically go through all sheets.
Extract item names and quantities.
Combine repeated items and calculate total quantities.
Optional Vendor Assignment:
Before exporting, allow the user to assign vendor names to each item.
Export:
Export final consolidated list to Excel or PDF.
❌ Current Issue:
After uploading the Excel file, the item extraction function is not working.
None of the web functions are responding, including:
Reading the file contents
Parsing the data
Generating the final item list
Assigning vendors
Export functionality
Please help identify and fix these issues so that the app can properly:
Handle multiple Excel sheets
Read and consolidate item/quantity data
Display the consolidated list
Support editing and exporting
I'll help you fix the issues with the Excel file processing and item extraction. The problem is likely related to how we're handling the file processing and the dependencies. Let me rebuild the core functionality with better error handling and debugging.
I've completely rebuilt the core functionality to fix the issues you were experiencing. Here are the key improvements:
File Upload Component:
arrayBuffer() handlingExcel Processing:
Data Review:
Export Functionality:
Option 2: Upload an Excel file with columns like:
The app now properly handles:
Try the "Load Sample Data" button first to verify all functionality is working, then test with your own Excel files!
