Fix Java Excel Handling
Budget: €30 – €250 EUR
My Java-based desktop application currently throws errors whenever a user tries to import an Excel file, and the files it exports need a small formatting tweak before they are usable. The rest of the program works well, so I’m looking for someone who can go straight to the file-handling layer, diagnose the functional bugs, and leave the UI and business logic untouched.
Here’s what I need from you:
• Identify and resolve the exception that appears during Excel import (the stack trace will be provided).
• Adjust the export file so that matches the format required (change date in american format to eu format).
• Keep the fixes confined to the existing codebase—no major rewrites—while following the project’s current build process (Maven, Java 8, Apache POI already in place).
Acceptance criteria
– Any sample Excel file I send imports without error.
– The exported file opens in Excel and matches the updated format exactly.
– No regressions in other file operations (read/write of CSV and TXT already supported).
I’ll give you the repo, a failing sample file. Let me know your estimated turnaround and if you’ve handled similar POI or file-IO bugs before.
