OmniDocHow to convert all Word formulas
Explain the idea of converting all the formulas in the document at once in Word: first determine the target format, then select Word's built-in conversion or online converter, and finally check whether the formulas are lost or deformed item by item.
Key points of this article
- Determine the target format first (convert the old formula to the new version, convert professional to linear, convert to LaTeX), use different tools for different goals
- Save a copy before conversion to prevent the original file from being unable to be rolled back
- Use Ctrl+A to select the entire text and check the number of formulas. Formulas in tables, text boxes, and footnotes are easy to miss.
- After conversion, zoom in to check superscripts, subscripts, fractions, radicals and numbers, and check important content
- Documents containing confidential content will be processed locally first, and uploaded online converters will be used sparingly.
If you have a paper, technical report or course handout of dozens of pages, with hundreds of formulas scattered in it, sometimes it needs to be unified into another form: for example, changing the objects of the old formula editor to the new formula, changing the professional display to linear format, or converting it into LaTeX code and handing it to the typesetting system. Manually modifying them one by one is slow, and it is easy to miss formulas in tables or footnotes. This article is written for students, researchers and document editors who need to batch process Word formulas.
After reading, you will know: first determine what kind of conversion you want, then choose Word's built-in conversion method or online converter, and finally how to check the results to confirm that the formula is not lost or deformed.
It should be noted that "formula conversion" has very different meanings in different scenarios. Some people want to make old formulas editable in the new version of Word, some people just want to switch the display mode, and some people need LaTeX source code. The goals are different, and the tools chosen and the focus of inspection are also different. Thinking about your goals clearly first will save more time than looking for tools directly.
How to convert all Word formulas? One sentence conclusion: Determine the target format first. If it can be completed in Word, do not export back and forth. If the file is sensitive or requires LaTeX, consider an online converter.
| your situation | Recommended practices | reason |
|---|---|---|
| The document contains an old version of the formula editor object. | Select the formula in Word and use the conversion function in the formula tool; if multiple selections are supported, you can process multiple places at once | After conversion, it becomes a new version of editable formulas, which can still be completed in Word without changing the file format. |
| Just want to switch between Professional and Linear formats | Right-click the formula, select the corresponding linear or professional option, and process it one by one or in sections | Only the display mode is changed, the content of the formula remains unchanged, and the risk is low |
| Need to convert the formula into LaTeX code | Import documents in UniDoc web editor (app.unidoc.top) and export using round-trip conversion between Word and LaTeX | Suitable for subsequent use of LaTeX for typesetting or version management |
| Document contains confidential data or contractual terms | Prioritize using the local Word or desktop client (download.omnidoc.top) for processing | Files do not need to be uploaded to a third party, reducing the risk of leakage |
| There are only one or two formulas | Manually modify or re-enter one by one | Batch tools also take time to check, which is not cost-effective. |
Before you start: Confirm these points first
1. Confirm the type of formula. Click the formula and see if the formula tool tab appears on the interface. If it appears, it means that it is an Office formula; if it is an old version of the formula object, the conversion method will be different; if it is a picture, it cannot be converted directly and you can only re-enter the formula. Different types will lead to different subsequent operations. You can avoid detours by making a judgment first.
2. Clarify the target format. Should you upgrade to a new version of the formula, switch to linear format, or convert to LaTeX? If the goal is not clear, it is easy to go around in one circle only to find that you have to go around again. Write your goals down on paper and compare them as you work.
3. Back up the original file first. Conversion will change the internal structure of the formula, and the spacing or font size of individual symbols may also change. Save a separate copy with "Before Conversion" added to the file name, so you can always go back to the original state if the results are not satisfactory.
4. Distribution of inventory formulas. Use Ctrl+A to select all text and observe what content is selected. Formulas in tables, text boxes, footnotes, and headers and footers may not be covered by the text selection and need to be checked separately. Otherwise, after the conversion is completed, you will think that everything has been processed, but in fact there are still some omissions.
- 5. Determine whether the file is sensitive. * unpublished data, contracts and internal technical materials are not suitable for uploading to unfamiliar online websites. This determines whether you use native tools or online tools later.
# steps to convert multiple formulas at a time in Word
- Save a copy. use "Save as" to save a new document, leaving the original document unchanged.
- all text checks. press Ctrl+A to select the full text, and pay attention to the selected formula object. If the conversion option appears in the formula tool, it can be processed in batches.
- try batch conversion. use the conversion function in the Formula tool when selected. If options are available, wait for the processing to complete, and do not close the file halfway.
- deal with the remaining formulas. if the batch option is not available, or if there is still an unconverted formula, click a single formula and use the conversion feature one by one. When there are a large number of formulas, it is recommended to deal with them in sections and check them once after the completion of each paragraph.
- uniform display mode. if you want to be unified as linear or professional, right-click the formula and select the corresponding option. Note that it is recommended to use only one display mode in the same document to avoid mixed arrangement.
- enlarge the check. * adjust the display ratio of the page to clearly identify the size of the superscript and subscript, fraction, root sign and summation sign of the formula page by page.
- Save as a new file. * after confirmation, save it as a new file name for subsequent comparison.
# check item by item after completion
The conversion is only half complete, and the check ensures that the results are available. The following suggestions are reviewed one by one:
| Check item | What do you think? | What if there's a problem? |
|---|---|---|
| Number of formulas | Browse page by page or browse with the navigation pane and count whether it is consistent with the original document. | The missing formula is selected separately and then converted. |
| Superscripts and fractions | Zoom in to see if the height of x ², fractional line and parentheses is normal. | Undo the conversion here and re-enter it with manual editing |
| Symbols and letters | Compare whether Greek letters, summation signs, and matrix square brackets are deformed or misplaced | Make amendments based on the original documents, not based on impressions. |
| Formula number and citation | Check whether the numbers (1), (2), etc., and references such as "see formula (3)" in the text still correspond. | Reinsert the number and update the fields and references in the document |
| Page typesetting | See if the formula is cut off at the page and whether the paragraph line spacing is abnormal. | Adjust the paragraph of the formula, or use the inline display instead |
| Output of online tools | Confirm whether the formula is still editable, whether the file is watermarked, and whether the original layout is retained. | Switch to other tools, or deal with it locally. |
The result of machine conversion needs to be checked manually, especially the derivation formula in the paper and the amount calculation formula in the contract. One symbol error may affect the meaning of the whole paragraph.
# which method is suitable for you?
- authors of papers and reports, files are not sensitive : convert them in batches in Word first, and then check them chapter by chapter against the original text. If you need to contribute to a journal that requires LaTeX source code, then import the converted document into the UniDoc web page editor and export. - users with unpublished data or contracts : only use local Word or desktop clients, do not upload the original files to the web version of the online converter. - only users who need a unified display mode : switch linear or professional models directly in Word without introducing any external tools. - users of online converters : check the file size limit before uploading, whether to add watermarks, whether to retain the editability of the formula, and whether to retain the original typesetting.
# frequently asked questions (FAQ)
1. What if the formula becomes a picture after conversion?
In most cases, the process of copying and pasting or saving the format converts the formula into a picture, as does the formula that is itself a picture in the original file. If you need to be editable, you should go back to the original file and reprocess it, or re-enter it with the formula tool.
2. Is it safe for online converters to process Word formulas?
Uploading a file means that the file has left the machine. Before dealing with draft papers, contracts, or internal materials, read the privacy instructions of the tool to confirm how long the file will be kept and whether it will be used for other purposes. When sensitive content is involved, it is recommended to use native software to handle it.
3. What should I look at when choosing a free online converter?
Focus on five items: file size limit, whether the output is watermarked, whether the formula is still editable, whether typesetting is retained, and whether the privacy description is clear. If you only look at the word "free", it is easy to encounter a watermark or format loss in the last step.
4. Why is the formula in Word different from that rendered by LaTeX after conversion?
The font, font size and spacing rules of different software are different, and the same formula will be displayed differently in different environments. Subject to the final submission or typesetting environment, make a final check in that environment.
# Summary
The key to batch conversion of Word formula is to first define the target format, then select the way that can be completed on this machine, and back up before conversion and check item by item after conversion. Batch conversion can save a lot of time, but superscripts, numbers and references still need to be manually confirmed. Go through this set of steps, and most documents can be converted smoothly.
