SLK at a glance
SLK
Convert to SLK when a legacy spreadsheet or import routine still expects symbolic-link style exchange files, especially in older finance, accounting, or reporting systems.
It is mainly useful for compatibility and archival migration.
For current spreadsheet exchange, XLSX, ODS, or CSV are usually more practical.
XLSX at a glance
XLSX
Convert to XLSX when recipients need an editable spreadsheet rather than a flat data export.
It is appropriate for financial models, reporting packs, planning templates, reconciliations, inventory sheets, and business deliverables where formulas, formatting, or multiple worksheets must survive.
Choose XLSX over CSV when workbook structure matters, and over PDF when users need to keep calculating, filtering, or annotating the data after delivery.
It is the practical target for spreadsheet collaboration inside office-centric organizations.
