I am just learning RoR and have a main goal for an application and wanted to see if there was a gem or multiple gems that I can use for my requirements below:
1. Upload an Excel file
2. Have the user map the user's column headers with our data titles (e.g., user has Zip on his/her Excel file and we have our title as Zip Code)
3. Applications will do a search for each product number on the Excel file that was uploaded and the result will be certain data points from the application's database
4. Results will be displayed and user will have the option to export the data back into Excel.
Any other suggestions or accomplishing this task are welcome!
Thank you in advance for the help!
