Workflow Playbook
Inspect CSV structure, keep the right columns, reshape rows, compare outputs, and split final files for dependable imports or reporting.
Hubs
A CSV cleanup workflow is reliable only when the file structure is known. Confirm the delimiter, encoding, header row, and row consistency before deleting columns or rewriting values. This is especially important when identifiers such as account numbers or postal codes should remain text.
Select only the columns that matter, reorder them to match the destination schema, and filter rows with a clear rule. If values need cleanup, transform them after the working schema is stable. Sorting and grouping help reviewers spot duplicates, missing categories, and unexpected totals before delivery.
Merge only compatible extracts, transpose only when layout is the real problem, and split files only after the master dataset is trusted. A final comparison against the expected spreadsheet version helps catch quiet header drift, dropped rows, and formatting changes before import or reporting.
Workflow playbook
Inspect delimiter, encoding, header consistency, and malformed rows before making cleanup decisions.
Keep the needed columns, reorder them into downstream order, and remove rows that clearly fall outside the target dataset.
Transform cell content, sort for reviewability, and group records when the consumer needs summarized or batched output.
Merge compatible CSV extracts into one master file, or transpose rows and columns when the source orientation blocks review or import.
Compare the cleaned CSV against the expected spreadsheet version, then split the validated master into per-team or per-batch outputs only if required.
Run detection and normalization when delimiter, encoding, header shape, or broken rows are uncertain.
Select or reorder columns when the schema is mostly right; transform values when formatting, casing, or derived fields must change.
Merge when multiple extracts should become one dataset, and split only after the cleaned master file has been validated.
