Where 5 MB matters

A 5,242,880-byte file: the size of a phone photo and the minimum part size for S3 multipart uploads. These are the default limits a file of this size is useful for testing:

System	Limit	Note
PHP	2 MB per uploaded file by default (upload_max_filesize)	A 5 MB upload fails on an untuned PHP installation.
Vercel Functions	4.5 MB request body	Larger uploads must go directly to object storage.
Amazon S3 multipart upload	5 MiB minimum part size	This file is exactly one minimum part.
AWS Lambda	6 MB synchronous invocation payload	5 MB of binary data exceeds it once base64-encoded.
Browser localStorage	About 5 MB per origin	Storing this file as text fills the quota.
Django	2.5 MB in memory by default	Larger uploads are streamed to a temporary file instead of held in memory.

Testing notes for XLSX

A date cell is a number with a format; importers that ignore the format show values such as 45123 instead of a date.
Reading a large workbook with a DOM-style library can use many times the file size in memory. Test with the 5 MB and 10 MB samples and prefer streaming readers.
