How to expand record column dynamically with Power Query

[Parth_1]

I am expanding the specifications column. The available data is expanding successfully. But when the records are aaded in future in specification column it does not expand it all. 
What query will help in expanding the records dynamically. Below are the images of record column and the query of expanding.

Thanks in advance.

@Parth_1 if all records have the same set of fields then read field names into some variable using Record.FieldNames(your_table[specifications]{0}) and use it in expand step. 

[Parth_1]

= Table.ExpandRecordColumn(#"Reordered Columns", "specifications",Record.FieldNames(product_data[specifications]{0}))

As per your suggestion I Expanded the column with above code but it does not expanding all the records in specification column itself.

@Parth_1 make sure that product_data has valid records in specifications column. Try solution provided by @wdx223_Daniel but still pay attention to product_data table.

I try to tackle the same issue but keep getting the error that there is a loop. How can I make sure i indicate the right column?

hi @Parth_1 
Intermediate steps containing the dynamic list of all column names would be required.

in the step shown in the screenshot, you would input the step name instead of the hard-coded values.

Kindly provide a sample input masking sensitive data incase further troubleshooting is required.
