I’m looking for quick help fixing the data formats inside a single CSV that stores my Google-exported sales records. All the information is present, but several columns are stuck in inconsistent or plain-text formats that prevent smooth sorting, filtering, and importing into dashboards. Here’s what I need: • Identify every column with formatting issues (dates, currency, numbers, etc.). • Convert those fields to a consistent, machine-readable format while keeping the underlying values intact. • Return the cleaned CSV plus a short changelog that lists each column you modified and the rule you applied.
