Introduction

In today's digital age, generating multiple PDFs from a database has become a crucial task for various industries, including finance, healthcare, and education. With the increasing demand for data-driven insights, organizations need to find efficient ways to extract and present data in a readable format. In this article, we will explore the process of generating multiple PDFs from a database using Excel and other tools.

Using Excel and VBA

One of the most popular methods for generating multiple PDFs from a database is using Excel and VBA (Visual Basic for Applications). Excel is a powerful spreadsheet software that allows users to create and manage large datasets. With VBA, you can automate tasks and create custom applications to perform complex operations.

To generate multiple PDFs from an Excel table, follow these steps:

Create an Excel table: Design an Excel table with the required columns and data. You can use Excel's built-in functions to perform calculations and data manipulation.
Create a VBA script: Open the Visual Basic Editor in Excel by pressing Alt + F11 or navigating to Developer > Visual Basic. Create a new module and write a VBA script to iterate through the Excel table and generate PDFs.
Use the ADODB library: The ADODB library allows you to connect to various databases, including Excel tables. Use the ADODB.Connection object to establish a connection to the Excel table.
Use the Acrobat library: The Acrobat library provides a set of APIs to interact with Adobe Acrobat. Use the Acrobat.PDF object to create and manipulate PDFs.
Generate PDFs: Iterate through the Excel table and use the Acrobat.PDF object to create a new PDF for each row. You can customize the PDF layout, font, and content using the Acrobat.PDF object.

Here is an example VBA script to generate multiple PDFs from an Excel table:

Sub GeneratePDFs()
    Dim db As ADODB.Connection
    Dim rs As ADODB.Recordset
    Dim pdf As Acrobat.PDF
    Dim i As Integer
&#39; Establish a connection to the Excel table
Set db = New ADODB.Connection
db.Open &quot;Provider=Microsoft.ACE.OLEDB.12.0;Data Source=&quot; &amp; ThisWorkbook.FullName &amp; &quot;;Extended Properties=&quot;&quot;Excel 12.0 Xml;HDR=YES&quot;&quot;&quot;

&#39; Create a recordset to iterate through the Excel table
Set rs = New ADODB.Recordset
rs.Open &quot;SELECT * FROM [Sheet1$]&quot;, db, adOpenStatic, adLockOptimistic

&#39; Create a new PDF for each row
For i = 1 To rs.RecordCount
    Set pdf = New Acrobat.PDF
    pdf.CreateDocument
    
    &#39; Customize the PDF layout, font, and content
    pdf.AddPage
    pdf.SetFont &quot;Arial&quot;, 12
    pdf.SetText &quot;Hello World!&quot;, 10, 10
    
    &#39; Save the PDF to a file
    pdf.SaveAs &quot;C:\PDFs\PDF&quot; &amp; i &amp; &quot;.pdf&quot;
    
    &#39; Release resources
    Set pdf = Nothing
Next i

&#39; Release resources
rs.Close
Set rs = Nothing
db.Close
Set db = Nothing

End Sub

Using Adobe Acrobat

Adobe Acrobat is a powerful tool for creating and manipulating PDFs. You can use Adobe Acrobat to generate multiple PDFs from a database by creating a custom script using the Acrobat library.

To generate multiple PDFs from a database using Adobe Acrobat, follow these steps:

Create a new PDF: Open Adobe Acrobat and create a new PDF document.
Use the Acrobat library: The Acrobat library provides a set of APIs to interact with Adobe Acrobat. Use the Acrobat.PDF object to create and manipulate PDFs.
Connect to the database: Use the ADODB library to connect to the database and retrieve the required data.
Generate PDFs: Iterate through the database and use the Acrobat.PDF object to create a new PDF for each row. You can customize the PDF layout, font, and content using the Acrobat.PDF object.
Save the PDFs: Save each PDF to a file using the Acrobat.PDF object.

Here is an example script to generate multiple PDFs from a database using Adobe Acrobat:

// Create a new PDF
var pdf = new Acrobat.PDF();
// Connect to the database
var db = new ADODB.Connection();
db.Open("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + ThisWorkbook.FullName + ";Extended Properties=&quot;Excel 12.0 Xml;HDR=YES&quot;");
// Create a recordset to iterate through the database
var rs = new ADODB.Recordset();
rs.Open("SELECT * FROM [Sheet1$]", db, adOpenStatic, adLockOptimistic);
// Generate PDFs
for (var i = 1; i <= rs.RecordCount; i++) {
// Create a new PDF for each row
var pdf = new Acrobat.PDF();
pdf.CreateDocument();
// Customize the PDF layout, font, and content
pdf.AddPage();
pdf.SetFont(&quot;Arial&quot;, 12);
pdf.SetText(&quot;Hello World!&quot;, 10, 10);

// Save the PDF to a file
pdf.SaveAs(&quot;C:\\PDFs\\PDF&quot; + i + &quot;.pdf&quot;);

// Release resources
pdf = null;

}
// Release resources
rs.Close();
rs = null;
db.Close();
db = null;

Using a Relational Database

A relational database is a type of database that stores data in tables with well-defined relationships between them. You can use a relational database to generate multiple PDFs from a database by creating a custom script using the ADODB library.

To generate multiple PDFs from a relational database, follow these steps:

Create a new database: Design a new database with the required tables and relationships.
Connect to the database: Use the ADODB library to connect to the database and retrieve the required data.
Generate PDFs: Iterate through the database and use the Acrobat.PDF object to create a new PDF for each row. You can customize the PDF layout, font, and content using the Acrobat.PDF object.
Save the PDFs: Save each PDF to a file using the Acrobat.PDF object.

Here is an example script to generate multiple PDFs from a relational database:

Sub GeneratePDFs()
    Dim db As ADODB.Connection
    Dim rs As ADODB.Recordset
    Dim pdf As Acrobat.PDF
    Dim i As Integer
&#39; Establish a connection to the database
Set db = New ADODB.Connection
db.Open &quot;Provider=Microsoft.ACE.OLEDB.12.0;Data Source=&quot; &amp; ThisWorkbook.FullName &amp; &quot;;Extended Properties=&quot;&quot;Excel 12.0 Xml;HDR=YES&quot;&quot;&quot;

&#39; Create a recordset to iterate through the database
Set rs = New ADODB.Recordset
rs.Open &quot;SELECT * FROM [Customers]&quot;, db, adOpenStatic, adLockOptimistic

&#39; Generate PDFs
For i = 1 To rs.RecordCount
    &#39; Create a new PDF for each row
    Set pdf = New Acrobat.PDF
    pdf.CreateDocument
    
    &#39; Customize the PDF layout, font, and content
    pdf.AddPage
    pdf.SetFont &quot;Arial&quot;, 12
    pdf.SetText &quot;Customer Name: &quot; &amp; rs.Fields(&quot;CustomerName&quot;).Value, 10, 10
    
    &#39; Save the PDF to a file
    pdf.SaveAs &quot;C:\PDFs\PDF&quot; &amp; i &amp; &quot;.pdf&quot;
    
    &#39; Release resources
    Set pdf = Nothing
Next i

&#39; Release resources
rs.Close
Set rs = Nothing
db.Close
Set db = Nothing

End Sub
