ChatGPT Answer Cleaner: Paste AI Answers Into Email, Word and Excel

Why AI answers look messy when you paste them

ChatGPT, Claude and Gemini write their answers in Markdown, a simple way of marking formatting with symbols. Two asterisks around a word mean bold, a line that starts with ### is a heading, a dash starts a bullet point and a row of | characters builds a table. The chat window reads those symbols and shows you neat formatting, so you never see them.

The copy button under an answer copies the Markdown itself, not the formatting you saw. On the OpenAI community forum, a staff member described this as a deliberate trade-off rather than a bug. Outlook, Gmail, Word, Teams and Excel do not read Markdown, so the symbols arrive as plain characters:

Fixing that by hand means deleting every asterisk and rebuilding every table. This tool does it in one step.

What the tool gives you

How to use it

1. In ChatGPT (or Claude, Gemini, Copilot), press the copy button under the answer. Paste it into box 1.
2. Pick a tab. The preview updates as you type or change an option.
3. Press Copy for email / Word, Copy plain text or Copy for Excel, then paste where you need it. In Excel, click one cell first; the table fills the cells from there.

Use the copy button rather than selecting the answer with the mouse. The button gives the tool the Markdown symbols it needs to rebuild headings, lists and tables. Text selected from the page has already lost them.

The options

• Remove the AI's opening and closing lines deletes a first line such as "Sure! Here's a summary:" and a last line such as "Would you like me to turn this into an email?". The tool only removes lines that clearly talk to you, and it shows every line it removed so you can untick the box if it took too much. It leaves ordinary sign-offs like "Let me know if you have questions" alone, because those are often part of the email you asked for.
• Turn simple maths into normal text changes AI maths notation such as \( 12 \times 8 \), \frac{a}{b} and x^{2} into 12 × 8, a/b and x². Long formulas will still look rough. For those, ask the AI to "write the formula in plain text".
• Remove emoji is off by default. Turn it on for formal emails.
• Plain punctuation turns curly quotes into straight ones and long dashes into a short hyphen. Chinese quotation marks and dashes next to Chinese text are left as they are.
• Font, size and headings apply to the Email & Word copy and the .docx file. If headings look too big in an email, choose "Make them bold text".

Can you do this without a tool?

• Select the answer with the mouse and copy. This often keeps bold and lists, but it can also bring the website's fonts and colours, and tables do not always survive.
• Google Docs has a built-in option. Turn on Tools → Preferences → Enable Markdown, then use Edit → Paste from Markdown. Google announced this feature in July 2024.
• Ask the AI for plain text. Adding "no Markdown, plain text only" to your prompt works, but you lose the bold, the headings and the tables, and the AI sometimes forgets on the next answer.

How this tool was tested

Before publishing, I ran 166 automated checks on the publish version of this page. Last full run: 25 October 2026.

• 141 checks in the browser (a Chromium-based browser, the engine behind Chrome and Edge, at phone width, 375 px):
  • 50 on reading Markdown: bold and italic, links, headings, nested lists, quotes, code and tables.
  • 16 on maths, 13 on the clean-up options and 25 on the outputs and the .docx and .xlsx files.
  • 37 on the buttons, the language switch and the page layout.
  The tests include tricky cases such as 5 * 3 * 2, file_name_v2.xlsx, "about ~5 minutes", dollar amounts, and an email that ends with "Let me know if you have any questions." None of them should change, and none did.
• 25 checks in real Microsoft Word and Excel (Microsoft 365 on Windows). The downloaded files opened without errors and kept their headings, tables, links, numbers and percentages. I also pasted the copied text in: Copy for email / Word gave real Word headings, bold, lists and a table, and Copy for Excel filled 4 rows by 5 columns of separate cells.

What the tests do not cover: I did not paste into Outlook, Gmail or Google Docs, I did not test on a Mac, and I did not use Firefox or Safari. The sample answer was written by me in the same Markdown style that chatbots use; it is not a saved ChatGPT reply. If an answer comes out wrong, please send me the Markdown on the Contact page.

FAQ

Is my text uploaded anywhere?

No. The conversion runs as a small script in this page, and the files are built in your browser too. Nothing is saved: close the tab and it is gone.

Which AI chatbots does it work with?

Any chatbot that writes Markdown: ChatGPT, Claude, Gemini, Copilot, DeepSeek, Perplexity and others. It also works for Markdown that you wrote yourself.

Does it change what the AI wrote?

No. It only changes formatting. The one exception is the opening and closing lines option, which deletes whole lines and lists them below the preview. Always read AI text before you send it, because the tool does not check facts.

Why are some table values not numbers in Excel?

In the .xlsx file, plain numbers such as 1,200 or 4.5 and percentages such as 84% become real numbers. Values with currency signs or units, such as $1,200 or 30 min, stay as text so nothing is guessed. When you paste with Copy for Excel, Excel converts values its own way.

What page size does the .docx file use?

A4 with 2.5 cm (1 inch) margins. In Word you can change it under Layout → Size.

Does it work with Chinese answers?

Yes. Chinese headings, lists and tables work the same way, and the whole page can be switched to Chinese with the button at the top right.
