How to rewrite an informal text to sound formal

Formal is not longer. That is the mistake most people make when they try to dress a message up. They keep the same sentence and bolt words onto it, and the result reads like a casual text wearing a borrowed suit.

Three things actually change when a message moves from casual to formal, and word count is not one of them.

What formal actually changes

Distance. Casual writing assumes the reader already knows the context. Formal writing supplies it. "Friday still ok?" becomes "Are we still meeting at 2pm on Friday about the Q4 forecast?"

Structure. A casual text is one long breath. A formal one has an order: what this is about, what you need, what happens next.

Commitment. Casual hedges everywhere. "maybe", "kinda", "if that works I guess". Formal states a position and leaves room for the other person to disagree with it.

The five moves

Run these in order. They take about thirty seconds.

• Expand contractions and drop filler openers like "hey so" and "just wondering".
• Put the ask in its own sentence, near the top, in plain words.
• Add the missing context the reader needs: a date, a name, a document, an amount.
• Answer the obvious objection before it gets raised.
• End with the next step and who owns it.

That is it. No thesaurus.

The trap on the other side

Formal has a failure mode, and it is worse than being too casual. Over correction reads as cold, or worse, as someone hiding.

Watch for these:

• Passive voice used to avoid saying who did something. "The deadline was missed" tells the reader you are managing them.
• Stacked politeness. "I was wondering if it might perhaps be possible" is four hedges around one question.
• Corporate nouns instead of verbs. "Please action the request" is not more professional than "Please approve it".
• Formality with someone you speak to daily. Sudden distance reads as anger.

The target is clear and considerate, not stiff. If you would not say the sentence out loud to the person, it is too far.

Reread it once

Before you send, check these four.

• Is the ask in one sentence, and could a stranger identify it?
• Is there a date, a number or a name where the reader will look for one?
• Have I removed every hedge that does not change the meaning?
• Does the last line say what happens next?

Most messages fail on the second and the fourth. Fix those two and the message reads professional without a single longer word.
