FORMAT QUESTIONS
About SDC files
What is SDC best used for?
SDC works especially well for recovering worksheets and formulas into a modern workbook or fixed PDF.
What can change during conversion?
Formulas, charts, macros, number formats, and print ranges may require review. Features that do not exist in the chosen output format cannot be carried across exactly.
Should I keep the original SDC file?
Yes. Keep the original until you have opened the result and checked its layout, quality, data, media tracks, or other important details.
