Power Query names each transformation step for you. Those
names often appear as quoted identifiers like #"Changed Type"
or #"Filtered Rows 1". This clutters the code,
making each step harder to scan and reference.
PQM Stepper helps to rename those steps to short, consistent identifiers using a mapping
schema all in one go. The logic stays the same, only the step names change, so queries become
easier to read and maintain.
