In my blog, below post already has a way to read an Excel (csv) file through SORT
https://mainframesf1.com/2012/03/28/sort-parse-read-excel-csv-in-mainframes/
Other approach we use in our shop is provided below.
In the Excel file, for each column, set the column width by right clicking the column and choosing “Column Width” and providing a fixed width value that you want. For example, if a max value for your account number is 10, choose 10 as “Column Width”
If you have a numeric value (with 2 decimals), ensure to choose the format as numeric (with 2 decimals) by right click on the Excel column and choosing Format cells. This will ensure that if you have any values as 1.2, it populates as 1.20 to give fixed width
If you have any text columns, it is preferred to right click the Excel column and choose Text in the Format cells. This will ensure all the data in the column is left justified. By doing this any cell value that is only numeric also will be left justified.
Once you have done all above, you can use “Save as” and choose the format “PRN” (Formatted Text (space delimited). This will save the Excel file as a text file in fixed width.
This “PRN” format file can now be FTP to a mainframe FB PS dataset with the required LRECL and used to process in a COBOL program by reading the file into a COPYBOOK layout in the layout as your input dataset is.
