odslint checks a Calc spreadsheet for the mistakes a spreadsheet actually makes:
a formula that breaks the pattern of the block around it, a number stored as
text, a hardcoded rate buried in a formula, an address spelled out where a named
range already exists.

Tools > odslint > Lint This Sheet reports the findings, jumps to the cell behind
each one, and can apply the mechanical fixes in a single undoable step.

Requires the odslint command line tool:  pip install --user odslint
