This would get the sheet named “Sheet 1” from “my-workbook.xlsx” and save as sheet1.json
xlsx2json my-workbook.xlsx "Sheet 1" > sheet1.json
This would get the number of sheets in the workbook
xlsx2json -count my-workbook.xlsx
This will output the title of the sheets in the workbook
xlsx2json -sheets my-workbook.xlsx
Putting it all together in a shell script and convert all sheets to into JSON documents..
xlsx2json -n my-workbook.xlsx | while read SHEET_NAME; do
xlsx2json my-workbook.xlsx "$SHEET_NAME" > \
"${SHEET_NAME// /-}.json"
done
