Frequently asked questions

What does EML viewer do?

Open a saved email and read it — sender, date, subject and body — with no mail client.

When would I actually use this?

Reading a message exported from a mailbox you no longer have open, pulling the attachments out of one, and turning an mbox export — one long file holding a whole folder — back into messages you can open one at a time.

What is the most common mistake?

Reading a raw header as if it were text. Any header may be encoded, so a subject with accents arrives as base64 and shows as gibberish taken literally. The matching trap is in the body: a line that happens to begin "From " is not a message boundary, and treating it as one cuts the message in half without changing the message count.

How is EML viewer different from EML to HTML?

They sit next to each other but answer different questions: EML to HTML is the one to open when you need it to save the HTML part of an email as a standalone page you can open in a browser. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

EML to text is the closest one after this: Pull the readable text out of a saved email, decoding quoted-printable and base64 bodies.

What else is worth having open alongside it?

MBOX to EML and MBOX viewer — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Messages are parsed against the mail and MIME specifications, in the browser, so nothing is sent anywhere — which matters more for mail than for most files. The mbox separator is matched on its full shape, sender and date together, rather than on the two words it starts with.

ExplainerConverting Formulas to Values Keeps the Cached Answer, Not the CalculationA spreadsheet file stores both the formula and the last answer Excel computed. Stripping the formula leaves the stored answer — and leaves a blank wherever the file never carried one.ExplainerThe Number 1 and the Text "1" Are Not DuplicatesDeduplication compares whole rows exactly, cell type included. Five identical-looking rows came out as three, because one held a number, one a string and one a string with a leading space.ComparisonZIP or TAR: Which One, and Why It MattersOne structural difference explains everything else: TAR does not compress, it only stacks; ZIP compresses each file on its own.
