File Size Limits and Supported Formats

• Maximum file size: 50 MB per file
• Row limit: No hard row limit, but files with more than 500,000 rows may take longer to parse
• Column limit: No hard column limit, but AskBiz works best with datasets that have clear, named columns

• .csv — Comma-separated values (most reliable format)
• .xlsx — Microsoft Excel 2007+ workbooks
• .xls — Legacy Microsoft Excel workbooks

Other formats (PDF, JSON, TXT) are not currently supported for upload. If your data is in another format, convert it to CSV first.

If your file exceeds 50 MB:

• Split it — break the data into smaller files by date range or category
• Remove unnecessary columns — drop columns you don't need for analysis
• Summarise — if you have transaction-level data, aggregate to daily or weekly totals
• Use CSV — CSV files are typically smaller than equivalent Excel files
