How to convert SLK to CSV
- Add your .SLK file - drop it in the box above or click to browse.
- Convert it to .CSV in a few seconds.
- Download your new .CSV file.
What to expect
- Formulas stored in the
.slkare replaced by their computed values in.csv- there is no formula syntax in CSV. - Cell formatting, column widths, and number formats are not carried over; dates may appear as serial numbers depending on how the application exports them.
- Only the active sheet is exported - if the
.slkcontains multiple sheets, you must export each one separately.
Frequently asked questions
Can I convert SLK to CSV without Microsoft Excel?
Yes - LibreOffice Calc and Google Sheets both open SYLK files natively and export CSV for free.
Will my data transfer accurately?
Cell values transfer correctly; formulas are replaced by their results and formatting is lost, but the raw data is fully preserved.
Why does Excel show 'SYLK: File format is not valid'?
Excel triggers this when it misidentifies a non-SYLK file as SYLK, which is common when the first cell contains 'ID'. Try opening the file via Data > From Text/CSV instead of double-clicking.
Which delimiter does the exported CSV use?
A comma is the default in all major applications; LibreOffice and our on-page converter let you confirm or change the delimiter before saving.
