Comments
Yet another format used to share spreadsheet information with business graphics applications.


The Microsoft SYLK (Symbolic Link) format is used mainly for the interchange of spreadsheet data between applications such as Microsoft Multiplan and Excel. Files in this format might also be imported directly by business graphics applications. SYLK files are written entirely in ASCII and, like Lotus DIF and SDI, are application-independent. SYLK, however, incorporates several features not found in other spreadsheet data interchange formats.

File Organization

Records in a SYLK file contain three fields: a Record Type Descriptor (RTD), a Field Type Descriptor (FTD), and a variable amount of data. A SYLK record has the following format:

<RTD>;<FTD>;<data> ...

File Details

The following Record Type Descriptors (RTDs) are currently defined by SYLK:

RTD

Description

B

Cell boundary

C

A data cell

E

End of file

F

Cell formatting parameter

ID

SYLK file identification record

NE

Link to an inactive spreadsheet file

NN

Name given to a rectangluar area of cells

NU

Substitute filename

P

Time and date stamp formats

Each Record Type Decriptor may be followed by a single Field Type Descriptor (FTD) if needed. Most field type descriptors have meanings unique to each record, but a few, listed below, have meanings global to all record types:

FTD

Description

W

Column width

X

Horizontal cell coordinate

Y

Vertical cell coordinate

The SYLK file format does not contain a header and resembles a data stream in its design. Except for the ID record, which must be the first record in every SYLK file, RTDs may appear anywhere in the file with the following exceptions:
