SLK to XLSX

Upload a SLK spreadsheet and save it as XLSX for editing, exchange or archiving.

SLK is a spreadsheet file format. Inettools converters use it for uploading and converting tabular documents between supported formats.

XLSX is a more modern version of the spreadsheet format, a type of e-book within the Microsoft Office Excel suite. It takes its name from the Microsoft Excel Open XML Document. This format has replaced the XLS. Initially included in the paid package of MS Office, but then the Open XML standard was recognized as public. As in XLS, the data is placed in the cells of the table, however, it uses data compression like ZIP. This reduces file size and increases the potential for data security. Data can be entered into the cells manually, as well as by automatic calculations - when special formulas are entered into the cells, starting with the equal sign.
