In this guide, you will learn how to upload data into Dolfin, whether for transaction tables, KPIs, invoices, etc. The process will be the same for any type of table within Dolfin. We have separated this guide into different sections:
How to prepare your data file?
To prepare your table, you’ll need to use a tool like Microsoft Excel or Google Sheets. Once you have created the table, you need to check how the following data is composed:
Date format
When entering a date in a cell, make sure the date format is the same in all date columns and that the formats are readable by Dolfin. We recommend using the following format: M/D/YYYY (Example: 1/27/2024).
Decimal and thousand separators
When entering numerical values, it’s important that all columns have the same format and ensure that the program you are using recognizes these values as numbers.
For example, when writing the number 1,230.50 the thousand separator is a comma, and the decimal is a period.
Save the file as CSV
Once you have finished creating your table, you can save it as a CSV. We recommend saving the table as a comma-delimited CSV.
Here is an example of a format you can use in your program:
nombre | valor_transacción | fecha_cierrre | fecha_factura | |
John Doe | 1,250.55 | 12/23/2024 | 12/28/2024 | |
Maria Vargas | 3,568.44 | 7/14/2024 | 12/20/2024 |
How to import the CSV file?
Once you have the file saved on your computer, you can upload it into Dolfin by following these steps:
Go to the Data section.
Select the table you want to upload the file to.
Click Import.
Upload the file from your computer and correctly select your file format—this is usually identified automatically.
How to map the data you uploaded?
Select the column in Dolfin corresponding to the properties in your CSV table. You only need to do this mapping once—afterwards, it will be recognized automatically in future imports.
Once you’ve finished this process, click Continue.
Key Selection (ID)
A unique key is required to link the imported data with existing data and prevent duplicates. If you don’t have a unique identifier, you can use a combination of columns to uniquely identify each row.
You have two options here:
Use a single column: If the values in the column are unique, you can use it as a unique key. This is the simplest option and works well when you have a column with unique values.
Use a composed key: If the values in the column are not unique, you can use a combination of columns to create a unique key. This is useful when you have several columns that together form a unique identifier.
Once you have completed this step, click Continue. You will see a preview before uploading the data into Dolfin, to confirm that everything is correct.
