How to enter, number and save online Word formulas

Key points of this article

The entry for inserting formulas in the web page editor is based on the page. First place the cursor at the paragraph position where the formula is to be inserted, and then the formula will enter the text flow.
If automatic numbering is not available, you can use a right-aligned one-paragraph format or a three-column table without borders to manually number. Numbering and formulas are easier to align.
Export .docx when you need to hand it over to others for modification or submission, and generate a sharing link only when you want to view it online. The two cannot be mixed.
After exporting, close the page, reopen the file, and check the formula structure, numbering sequence, and references in the text one by one.

If you have a paper, handout, or technical report in which you need several numbered formulas, but don't want to install desktop office software on your local computer, you will go to the Word formula online editor. The real trouble is often not the input itself, but three things: how to put the formula into the text, how to number multiple formulas uniformly, and how to save it into a Word file that others can open after finishing it.

This article takes the UniDoc web page editor (app.unidoc.top) as an example to explain the operation sequence and judgment basis of these three steps. By the time you finish reading, you should be able to insert a formula into a web page, number it, choose how to save or export it, and finally use a checklist to make sure the results are not aliased.

The specific entrance and interface are subject to the page. The following describes the general operation directions.

How to enter, number and save online Word formulas? One sentence conclusion

Let’s get straight to the conclusion: Insert the formula object in the UniDoc web editor and enter the content; if there is no automatic function available for the numbering, manually format it in the same paragraph or table; export the .docx when a Word file is needed, and open it in desktop Word for verification.

your situation	Recommended practices	reason
There are only one or two formulas, and they have to be handed over to others.	Export .docx after typing in web page	Word files are universal and the recipient does not have to use the same web page
There are many formulas and they need to be numbered uniformly and cited in the text.	Use right-aligned numbering format, and the numbers are manually incremented	References need to be checked manually, and the unified format is less likely to be messed up.
Get used to writing formulas in LaTeX	Keep the LaTeX source code and export it at the same time	The source code can be returned to the LaTeX environment to continue compilation and typesetting.
Need to send to colleagues online for review	Generate a sharing link and save it as .docx	Links are easy to browse, and files are easy to archive and re-edit.
Need to fine-tune the layout or review and revise it	Export to .docx and adjust in desktop Word	Fine typesetting is usually more convenient on the desktop

Before you start: Confirm these points first

Confirm end use. Submissions, assignments and internal reports have different format requirements. Submission requirements should be based on the journal or school template. Different uses have different export formats and numbering methods.
Confirm the numbering form. Commonly used are continuous numbers, such as formula (1), formula (2), and chapter numbers, such as formula (2.1). Decide on the form first, and you won’t have to change it again when you insert the formula later.
First clarify the content of the formula. Write down symbols, superscripts and subscripts, fractional levels and parenthetical relationships clearly on paper or in notes. The more complete the draft, the less rework will be required on the page.
Confirm the recipient’s software environment. .docx can be opened in common office software, but the fonts and spacing of formulas may be slightly different in different software. Please reserve time for checking important files.
Keep the original before exporting. Save a copy before making extensive changes so you can roll back if something goes wrong without having to re-enter it from scratch.

Steps to enter formulas in UniDoc web editor

Open app.unidoc.top, create a new document, or open an existing document.
Place the cursor at the paragraph where you want to insert the formula, and the formula will appear in the text flow, keeping the same order as the text.
Insert the formula object in the formula function of the editor, and an editable formula area will appear on the page.
Enter superscripts, subscripts, fractions, radicals and other structures layer by layer according to the draft, and check whether the brackets are matched after each layer of input.
Write text connections before and after the formula, such as "where x represents..." to let readers know the meaning of each symbol.
Check the Greek letters, the upper and lower limits of the summation and multiplication signs, and the rows and columns of the matrix one by one against the draft. If any errors are found, correct them immediately.
After every few formulas are completed, export a copy or write down the current progress to avoid accidentally losing content midway, and then continue to the next formula.

How to number formulas: automatic and manual methods

In fact, the function of automatic numbering of formulas is not listed, so first confirm whether there is an available numbering method in the editor. If yes, the actual function of the page shall prevail; if not, use one of the two manual layouts below.

Align the same paragraph right. The formula is centered and the number is written at the end of the same paragraph. Use spaces or tab stops to push the number to the right. The operation is simple, but the numbers will be squeezed when the formula is long, so it is suitable for documents with short formulas.
Three-column table without borders. Put formulas in the middle column, numbers in the right column, and remove all borders from the table. No matter how long the formula is, it will not be overloaded with numbers. It is suitable for papers with many formulas that need to be arranged neatly.

When numbers are maintained manually, text references must also be processed simultaneously. After writing "It can be seen from formula (2)", if the previous formula is added or deleted, the number will change accordingly, and all references must be checked one by one. If you retain the LaTeX source code, you can also use \tag to write the number in the source code, but the final display effect is subject to the rendering result of the editor.

Save and export: which format to choose

Save as web document: Continue to modify in the editor, suitable for drafts that are still iterating.
Export to Word (.docx): Suitable for submission, handing over to others for modification or archiving, and is the first choice for most scenarios.
Export LaTeX source code: Suitable for papers that require compilation and typesetting. The source code can continue to be processed in the local environment.
Export HTML: The editor supports lossless export, suitable for publishing to web pages.
Generate sharing link: Suitable for others to view online. Links are not equal to files. Do not assume that the other party can get the .docx. If you need the file, please export it separately and send it.

If you want to use the UniDoc document editor on the desktop, you can go to download.omnidoc.top to download the OmniDoc desktop client, which includes the editor.

Check each item after completion

Check items	How to see	What to do if there is a problem
formula structure	Compare fractions, superscripts and subscripts, radicals and brackets one by one against the draft	Go back to the web page to modify it, and then re-export it.
Numbering sequence	Read the number from beginning to end to see if it is continuous and there are no skipped numbers.	Adjust in sequence and modify text references simultaneously
In-text citation	Search for "formula (" and check whether the reference numbers are correct one by one.	Change to new numbering to avoid references pointing to wrong formulas
Layout alignment	Open it in the exported .docx and check whether the formula is centered and the numbers are aligned.	Adjust the layout and export again, or use a three-column table instead.
preserve integrity	Close and reopen the exported file to confirm that all formulas are in	Missing formulas are reinserted and exported again

❓ Frequently Asked Questions (FAQ)

1. Can the formulas in the web page be copied directly to Word on the desktop?

You can try it, but a safer method is to export .docx first and then open it in desktop Word. After copying and pasting, you still need to check the formula one by one, especially the superscripts, subscripts and brackets.

2. Can the formula number be automatically incremented?

In fact the autonumbering feature is not listed, please confirm in the editor first. If not, use the manual numbering method explained earlier, and check it after adding or deleting formulas.

3. Can the other party download my Word file when I share the link?

Don’t assume the other person has access to the .docx file. The shared link is suitable for online viewing. If you need a file, please export it as .docx and send it separately.

4. If the formula seen on the web page is rendered correctly, can it be used directly?

Correct rendering only means that there is no problem with the display, but it does not mean that the symbols and values are correct. Please compare the formula with the original manuscript or derivation process item by item, especially symbols that are easily confused.

📝 Summary

Complete the formula input in the Word formula online editor, use manual formatting to process the numbers, and then export the .docx and review it in desktop Word. These are the three key steps of this route. After each export, the file must be reopened to check to make sure that formulas, numbers, and references are not missing.
