Simplify dynamic file path references in Power Query for shared workbooks

Are you struggling with using the CELL("filepath") function to create dynamic source references in Power Query?

We have a straightforward opinion on this: the struggle to pass a dynamic file path from an Excel cell into a Power Query parameter is a textbook example of a tool demanding more from its users than it should. For days, this user has been chasing a solution, following instructions, and hitting walls. The frustration is not theirs alone, it is a pattern we see regularly, and it points to a deeper gap in how traditional spreadsheets handle modern, shared workflows.

What this means in practical terms is that the user has already done the hard part. They built a clean, reusable table with a formula that captures the workbook's current path. That is smart, human-centered thinking: make the data self-aware so that when the file moves or is shared, the references move with it. The problem is that Power Query, despite its power, treats that cell value as an afterthought. The steps to turn that cell into a usable parameter involve navigating the Power Query editor, creating a named parameter, writing M code to read from the table, and then referencing that parameter in every other query. Each step is documented somewhere, but none of them feel designed for a person who just wants their workbook to work.

The core issue here is not a lack of technical know-how. It is a lack of accessible, action-oriented design. The user found the right formula, identified the correct pattern for parameters, and still got stuck because the bridge between Excel's native functions and Power Query's environment is fragile. The instructions they found likely told them to "create a parameter from a cell" without explaining that the cell must be in a named table, that the table must be loaded as a connection-only query, and that the parameter must then reference that query's output. That is three or four hidden steps, each one a potential failure point. For a user who already understands LEFT, FIND, and CELL formulas, that barrier feels arbitrary.

Our take is that tools should meet users where they are, not where the documentation assumes they should be. The user's approach, building a dynamic path into the workbook itself, is the right one. The missing piece is a simpler bridge that lets that cell value flow into Power Query without requiring M-code gymnastics. Until that bridge exists, the practical advice is to treat the parameter creation as a separate, one-time setup ritual: create the named table, load it as a connection-only query, then manually edit the M code to reference that query's output. It is not elegant, but it works. The real lesson is that the future of data management depends on removing these friction points, so that smart solutions like dynamic file paths become the norm, not the workaround.

I've been trying for days to figure this out. I made a worksheet with one table named "File Path" and one entry with the formula =LEFT(CELL("filename"),FIND("]",CELL("filename"))) to give the current path to the workbook.

I have read that I can somehow add this as a parameter in Power Query, then reference this parameter in the source code for other tables in the workbook. I've tried to follow the various instructions I found, but so far no luck in getting the value from the cell into the parameter.
