A 2 MB CSV file, on demand.
Exactly 2,097,152 bytes of a comma-separated table with eight columns of plausible user records, built on your machine the moment you press the button.
2,097,152 bytes, exactly.
Every byte above the 80 bytes structural minimum goes into additional rows, with the final row padded to land on the exact byte, which is why this file still behaves like one a real user would send.
Unit convention
2 MB on this page means exactly 2,097,152 bytes, using the binary (MiB) convention some systems label "MB" for short. 1 MB in the strict decimal sense is 1,000,000 bytes; 1 MiB is 1,048,576 bytes — the readout above always shows the exact count either way.
Approximate size equivalents
Roughly 1,165 pages of typed text, 2 minutes of 128 kbps audio, 12 seconds of CD-quality audio. These figures compare file size only — the generated file does not contain this text, audio or image content.
Accepted by
PHP default upload_max_filesize, Discord free attachment, AWS API Gateway payload — all publish a limit at or above this size, based on commonly cited figures that can vary by plan and change over time.
Other CSV sizes
Default limits start biting here: PHP ships with a 2 MB cap, and many form builders stop at 5 MB.
Questions.
Is this 2 MB CSV file valid?
Yes. It is a comma-separated table with eight columns of plausible user records. The extra bytes sit in additional rows, with the final row padded to land on the exact byte, so it opens in Excel, Sheets, pandas and Python's csv module.
Does 2 MB mean 2,097,152 bytes?
On this page, yes — 2 MB uses the binary (MiB) convention, so the file is exactly 2,097,152 bytes. 1 MB in the strict decimal sense would be a different, smaller byte count. Upload validators may use either convention, so the exact byte count is always shown to remove any ambiguity.
What is a 2 MB file used for?
Default limits start biting here: PHP ships with a 2 MB cap, and many form builders stop at 5 MB. For CSV specifically, the usual job is testing data import limits and streaming parsers.
Where is the file downloaded from?
Nowhere. It is assembled in a Web Worker on your own device and handed to the browser as a Blob, so nothing is uploaded, fetched or stored.
