About This Feature
Overview
MIDB is a text function in WPS Sheets for Windows that extracts part of a string by byte length. It is useful for mixed-language text, double-byte characters, and data-cleaning tasks that require fixed byte-based extraction in a spreadsheet.
Core tasks include:
- Insert MIDB from the Insert Function dialog.
- Enter
=MIDB(...) directly in a cell or in the formula bar. - Review the syntax and parameter details before applying the formula.
System Requirements
| Item | Requirement |
|---|
| OS | A Windows device that can run WPS Office normally |
| App version | It is recommended to use the latest version of WPS Office |
| Network | No mandatory network connection is required for local formula entry and calculation; internet access is needed for online help or updates |
| Other | WPS Sheets should be installed, and you should have permission to open or edit spreadsheet files |

| Capability Summary | MIDB can be used in WPS Sheets through Insert Function or direct formula entry, making it suitable for byte-based text extraction in spreadsheet workflows. | Microsoft documents Mid and notes that MidB is used with byte data in strings for double-byte character set languages. | Google Sheets provides a MIDB function that returns part of a string starting at a given position and up to a specified number of bytes. | Notion formulas support substring() for position-based text extraction, but the official help page does not describe byte-based extraction. | Adobe Acrobat focuses on PDF editing, conversion, and signing, and its official product page does not describe spreadsheet text functions such as MIDB. |
| WPS Advantages | Advantage: WPS combines Insert Function, parameter guidance, and direct formula entry in the desktop spreadsheet interface for one continuous workflow. | Compared with WPS: Microsoft explains MidB behavior, but the referenced page is centered on Microsoft function documentation rather than a desktop spreadsheet insertion flow. | Compared with WPS: Google Sheets also supports MIDB, but the official guidance is help-page based; WPS provides a desktop formula dialog for direct entry and review. | Compared with WPS: Notion can extract text by position, but it does not present a MIDB-style byte-based function in the referenced formula guide. | Compared with WPS: Adobe Acrobat is built around PDF tasks rather than spreadsheet formula entry and byte-based text extraction. |

Overall Conclusion
MIDB in WPS is a practical fit for users who need byte-based text extraction in a Windows spreadsheet environment. Compared with online formula references or PDF-focused tools, WPS keeps the function entry path more direct for everyday spreadsheet work.
Use Cases
| # | Scenario | Target Users | Core Pain Point | Solution |
|---|
| 1 | Extract a fixed segment from a code string | Data staff | Long code strings are error-prone to split manually | Use MIDB to return content from a fixed byte position |
| 2 | Process mixed Chinese and English text | Office users | Standard character-based extraction may not match the expected result | Use MIDB for byte-based handling of double-byte text |
| 3 | Fill the same formula across many rows | Report creators | Re-entering the same formula repeatedly is inefficient | Enter MIDB once and copy it with the fill handle |
| 4 | Learn the function structure | New users | The meaning of each parameter is not clear at first | Review the parameter dialog and syntax details in Insert Function |
| 5 | Troubleshoot unexpected results | Advanced users | It can be hard to locate the cause of a wrong result | Check the start position, byte length, and referenced cells against the syntax |
