How to convert XLS to SLK
- Add your .XLS file - drop it in the box above or click to browse.
- Convert it to .SLK in a few seconds.
- Download your new .SLK file.
What to expect
- SLK saves only the active sheet - if your workbook has multiple sheets, export each one separately with a distinct filename.
- SYLK strips charts, images, macros, merged cells, conditional formatting, and named ranges; only cell values and basic formulas are retained.
- Non-ASCII characters such as accented letters or CJK text may not round-trip correctly depending on the reading application.
Frequently asked questions
Does Excel still support saving as SYLK?
Yes - use File > Save As and choose
SYLK (*.slk) from the type list. Excel shows a compatibility warning; click Yes to proceed.Can I convert a multi-sheet XLS into a single SLK file?
No. SLK holds only one sheet, so you must export each sheet separately and give each file a distinct name.
When should I choose SLK over CSV?
Only when a legacy system specifically requires
.slk and rejects CSV - CSV is simpler and more universally supported for plain data exchange.Will my formulas survive the conversion?
Basic formulas are retained, but complex functions, VBA macros, and all formatting rules are stripped by the SLK format.
