Solving upload problems

How upload works

basebox can process documents, spreadsheets, and audio files. If an upload doesn't work, it's usually due to the format, size, or technical limits.

Uploading files correctly:

  1. Start the upload – Click the paperclip icon or drag and drop the file into the chat
  2. Wait for processing – Wait for the "File uploaded successfully" confirmation
  3. Reference the file – Mention the file in your question: "Based on the uploaded file…"

Common problems and solutions

"Context window reached"

Problem: The chat is too full for further uploads Solution: Start a new chat

"File too large"

Problem: The file exceeds the 10 MB limit Solutions:

  • Compress the file
  • Split it into smaller parts
  • Extract only the relevant pages/sections

"Format not supported"

Common fixes:

  • .xls → .xlsx
  • .csv → .xlsx
  • .m4a → .mp3
  • .jpg → Copy and paste the text

Upload "hangs"

Solutions:

  • Reload the page
  • Try a different browser
  • Check your internet connection
  • Try a smaller file

Supported formats

Documents:

  • PDF – Text must be selectable
  • DOCX – Word documents
  • TXT – Plain text files
  • PPT/PPTX – PowerPoint presentations

Spreadsheets:

  • XLSX – Excel format (recommended)
  • XLS – Older Excel format

Audio:

  • WAV – Best quality for transcription
  • MP3 – Compressed, widely used
  • FLAC – Lossless compression
  • OGG – Open-source format

Maximum file size: 10 MB per file

Unsupported formats

These files do NOT work:

  • CSV – Convert to Excel (.xlsx)
  • Images (JPG, PNG) – Enter the text manually
  • Videos (MP4, AVI) – Extract the audio
  • Archives (ZIP, RAR) – Upload files individually

Tips for successful uploads

Check before uploading:

  • Format supported? See the list above
  • Under 10 MB? Check the file size
  • File not corrupted? Open and test it in another program

For PDF problems:

  • Is the text selectable? Try selecting the text
  • Scanned PDFs don't work – copy the text manually

For Excel problems:

  • Use the .xlsx format instead of .xls
  • Remove empty rows to reduce the file size
  • Remove password protection before uploading

Troubleshooting checklist

If the upload doesn't work:

  1. Start a new chat – The context window might be full
  2. Check the file format – Is it supported?
  3. Reduce the file size – Under 10 MB?
  4. Reload the browser – Fix cache issues
  5. Try a different browser – Chrome, Firefox, Safari
  6. Check your internet connection – Stable and fast enough?

If nothing helps:

  • Save the file in a different format
  • Copy and paste the content manually
  • Contact support

Important notes

  • Always wait for the upload confirmation
  • Reference the file in your question
  • If problems persist: start a new chat

Tip

Test problematic files first in a new chat with a simple question like "What does this file say?"
