Where 3 MB matters
A 3,145,728-byte file, 3 MB in the binary units that operating systems and upload limits use. It is useful wherever a form, an API gateway, a storage quota or a mail server is configured with a limit of about this size.
Use this file for
- Finding the first upload limit in a new stack
- Testing spreadsheet import alongside XLSX and CSV
- Checking date and number conversion
Testing notes for ODS
- Dates are real dates in ODS and serial numbers in XLSX, so code written for one format mishandles the other.
- Rows and cells can be run-length encoded with a "repeated" attribute. A sheet that looks empty may declare a million repeated rows, and a reader that expands them literally runs out of memory.
