xlsx

You can automate spreadsheet data cleaning by opening, editing, and restructuring tabular data across xlsx, xlsm, csv, and tsv formats to produce a finalized spreadsheet deliverable. This process applies formulas and formatting deterministically with reproducible outputs.

Yes, you can convert between tabular formats like csv and xlsx while simultaneously applying formulas, formatting, and basic data transformations. The workflow repackages the converted data into a final spreadsheet output.

openpyxl handles opening, editing, and formatting xlsx files, while an included LibreOffice-based workflow handles optional formula recalculation. This combination ensures deterministic spreadsheet operations with reproducible outputs.

The best way to clean messy spreadsheet data is to apply deterministic on-demand operations that open, edit, and restructure the input file. You can add computed columns, apply formulas, and format the data into a finalized spreadsheet.

Using python for spreadsheet automation supports opening, editing, and repackaging xlsm files, but complex macro execution is outside the scope of this workflow. It focuses on deterministic data processing, formatting, and optional formula recalculation rather than interactive macro scripting.

You do not need LibreOffice to convert tsv files to xlsx, as openpyxl handles reading and writing tabular formats. LibreOffice is only required if you need optional formula recalculation during the spreadsheet automation process.
