Understanding the DOCX Format Limitation
A .docx file is essentially a ZIP archive containing multiple XML files that define the document's structure, styles, and content. Power Query’s standard file connectors expect structured data like CSV, TSV, or plain text. It does not have a built-in parser for the complex internal structure of Word documents. Therefore, attempting to load a .docx file directly will result in an error or display unreadable binary garbage. The solution requires an intermediate step where the document is stripped of its markup and saved as a simple text stream.
Converting DOCX to Plain Text
The most reliable method to prepare your data is to save the Word document as plain text. Open your .docx file in Microsoft Word. Navigate to File > Save As. In the dropdown menu for file types, select Plain Text (*.txt). You may be prompted with encoding options; typically, UTF-8 is the safest choice for modern compatibility. Click Save. A dialog box will appear asking if you want to confirm the conversion; click Yes. This action creates a new file with the same name but a .txt extension, containing only the visible text from your document.
Alternatively, if you need to preserve some structural integrity like paragraphs or columns, you might consider saving as Tab-Separated Values (TSV) if your word processor supports it, though standard Word usually only offers plain text. For highly structured documents, copying specific tables into Excel before saving as text can also be a viable workaround, but this requires manual intervention. For automated bulk processing, the plain text route is preferred.
Loading the Text File via Power Query
Once you have your .txt file, place it in a known directory. Open Excel and go to the Data tab on the ribbon. Click on Get Data, then navigate to From File and select From Text/CSV. Browse to the location of your newly created text file and select it. Click Import.
Power Query Editor will open automatically. Here, you can preview the data. If your text file has line breaks that separate distinct records, Power Query might initially load the entire file as a single column. You need to split this column based on delimiters. Click on Split Column in the Transform tab and choose By Delimiter. Select Custom and enter a newline character or specify the delimiter used in your original document. If your document had tabs between fields, select Tab. If it was just continuous prose, you might leave it as one column or split by space depending on your needs.
After splitting, review the resulting columns. You can rename them, change data types, or remove unnecessary rows. When satisfied, click Close & Load. This will push the parsed data into a new Excel sheet. This process is repeatable. If you update the source text file, you can simply refresh the query in Excel to get the latest data.

Handling Encoding Issues
If the imported text shows strange characters, it is likely an encoding mismatch. In the Power Query Editor, go to Home > Transform > Change Type > Using Locale. Ensure the source encoding matches what was selected during the Word save operation. UTF-8 is generally recommended for international characters.
Alternative Approaches for Complex Documents
If your document contains images, headers, footers, or complex tables that plain text stripping removes, consider extracting specific parts manually before import. However, for pure text extraction, the method above is optimal. If you encounter issues with files not saving correctly during this process, refer to guides on Troubleshooting Word and Excel: Files Not Saving on Exit to ensure your environment is stable.
Frequently Asked Questions
Can Power Query read .docx files directly without conversion?
No, Power Query cannot directly parse the internal XML structure of .docx files. It requires the data to be in a flat format like CSV, TXT, or JSON. Conversion is a mandatory prerequisite step.
How do I handle line breaks in my text file?
In the Power Query Editor, use the Split Column feature. Choose Custom delimiter and select the Line Feed (\n) or Carriage Return (\r) option to separate lines into different rows or columns as needed.
What if my text file is very large?
Power Query handles large text files efficiently by streaming data. However, if the file exceeds memory limits, consider splitting it into smaller chunks beforehand or using VBA to process it in batches before loading into Excel.
Does this method preserve bold or italic formatting?
No, saving as plain text removes all formatting including bold, italics, fonts, and colors. Only the raw textual content remains. If you need formatted data, you must extract tables specifically or use third-party libraries.
Can I automate this process for multiple files?
Yes, you can create a folder-based query. Place all converted .txt files in one folder, then use From Folder in Power Query to combine them. This allows batch processing of many documents at once.
