Now upload above "ExcelToSPListItems.html" file into site assets library.
Step 3: Create an webpart page and save in Page library. Now edit this page and add Content Editor Webpart.
Step 4: To test the application first create an excel file with below values and save as "EmployeeDetails.xlsx".
Step 5: Now test the application. upload excel file and check in SharePoint list. Excel list must created or updated.
Perfect!!!
ReplyDeleteThe tutorial demonstrates a practical way to read Excel files directly in a browser using HTML5, jQuery, and SheetJS, then process the data for storage in a SharePoint list. The approach of validating the uploaded .xlsx or .xls file and converting worksheet data into JSON is especially useful for developers working on data-driven web applications. HTML CSS JavaScript Training fits well with these front-end concepts.
DeleteHi Man!
ReplyDeleteFirst of all, this is very superb post!!!
Appreciate if you can share code for SharePoint 2010?

ReplyDeleteis it feasible with morw then 50 columns and 5000 items, Appreciate if you can share your thoughts on this
ReplyDeleteThis is brilliant. Thanks for sharing!
ReplyDeleteThank for sharing. This is very helpful to me
ReplyDeletehi, I attempted to use this code but the 'choose file' button and the 'export to table and SPList' function never appeared. I followed the directions as stated above. Any help is appreciated, thanks
ReplyDeleteGreat post. Is it possible to do this for multiple excel uploads?
ReplyDeleteExcel is a powerful yet easy to use spreadsheet program. In many cases, Excel charts can be created to visually display complex information to the users. Excel 2010 has powerful new features to create impressive charts. ppt translator
