Description

The expASC function exports worksheet data as ASCII file.

Note that the ASCII export is limited to data-only worksheets. Complex documents containing embedded information -- report sheets, worksheets with embedded or linked graphs (including sparklines) -- cannot be exported to ASCII files. If the worksheet to be exported has embedded images and graphs, those images and graphs will be ignored during exporting.

Examples

This example is to export all sheets in all workbooks within the project to a specified navigated path and name those data files as "WorkbookName_WorksheetName". 

fdlog.openpath(B); // choose directory to store files
 
doc -e W{   // loop over all workbooks in project
 
       doc -e LW // loop over all worksheets in workbook
            {
              string temp$ = wks.name$; // Get worksheet short name
           // string temp$ = wks.longname$; // Run this line to get worksheet long name
              expASC type:=text path:=%B%H_%(temp$) shortname:=1; // Export files as .txt files with column short names exported
            };
}

A variation on this example exports all worksheet columns to .dat files and organizes them using the project's Project Explorer folder structure: 

string fname$ = "%YMap Data.opju";
doc -o %(fname$); // opens project User Files\Map Data.opju

doc -e W{   // loop over all workbooks in project
    
       doc -e LW // loop over all worksheets in workbook
            {
              string temp$ = wks.name$; // Get worksheet short name
           // string temp$ = wks.longname$; // Run this line to get worksheet long name
              expASC path:="<Project Folder><PE Path>%(temp$)" shortname:=1; // Export and organize files using PE folder structure
            };
}
