Parse data from uploaded CSV files into fields
Requirement
When users upload CSV files, their data is parsed and the values are inserted into the required fields of another form.
Use case
An order management app contains two forms, one to store purchased product details, and the other to store purchase list as CSV files. When a
n admin uploads a purchase list file in
the Upload Purchase List
form, its data will be parsed and inserted into the respective fields of
Products
form.
Steps to follow

|
Quantity

|
Currency
|
Selling Price

Selling_Price
|
The workflow is to be triggered when
Upload purchase list
form is successfully submitted,
so
we are selecting the
Form Event
as "Successful form submission".
3. Save the following Deluge script in the Deluge editor:
- //Extract the content from the uploaded input file and store in the variable fileContent as text
- fileContent = input.Purchase_List.content;
- // Parse the file content so the rowsList variable is structured such that each of its element is a text that corresponds to a row of the input CSV file
- rowsList = fileContent.tolist("\n");
- // Define a counter to keep track of the iteration
- count = 0;
- // Iterate through the rowsList to parse the elements of each row.
- for each rl in rowsList
- {
- if(count > 0)
- {
- // Split elements of the row and convert into a list
- elementsList = rl.tolist(",");
- // Add record into the Products form
- response = insert into Products
- [
- Added_User = zoho.loginuser
- Product_Name = elementsList.get(2)
- Unit_Of_Measure = elementsList.get(3)
- Quantity = elementsList.get(4)
- Selling_Price = elementsList.get(3)
- ];
- }
- // Increment the counter at the end of each iteration
- count = count + 1;
- }
See how it works
Points to note
-
The Deluge script provided in this tutorial is specific to the CSV files whose rows are separated with new lines and the first row contains header of the columns, which are in the order of Product Name, Unit Of Measure, Quantity, and Selling Price. Using this script for a CSV file of different format may not work as expected.
Please check the attachments for the sample file on which the provided Deluge script works.
-
This tutorial works best on files that usually contain only text values ( for example, .txt or .csv ).
