Odoo 19 introduces a more refined and flexible reporting framework that allows technical consultants to design professional printable documents and spreadsheet reports with enhanced precision. Whether you are generating financial statements, sales summaries or custom operational insights, QWeb reports and spreadsheet reports offer a stable and customizable reporting engine for complex business needs.
In this guide, we will walk through the technical workflow of creating custom QWeb templates, configuring ir.actions.report settings and building spreadsheet or XLSX reports with clean formatting and dynamic data. Let us explore how technical customization helps organizations move closer to automation and data accuracy.
Introduction to Odoo 19 Reporting Framework
The reporting engine in Odoo 19 is designed to give technical teams more freedom in controlling structure, design and output. QWeb reports handle PDF and HTML documents while spreadsheet reports manage dynamic tabular data for Excel export.
Understanding QWeb Report Engine in Odoo 19
QWeb uses XML expressions to structure tables, models and values. This allows detailed customization using record fields, loops and template inheritance. QWeb reports are ideal for invoices, delivery orders and branded printouts.
When to Use Spreadsheet Reports or XLSX Export
Spreadsheet reports are powerful when businesses require analytical exports. Odoo 19 spreadsheet or XLSX export is widely used for accountant related tasks, KPI monitoring and data comparison. It is ideal when printed formatting is not the priority but numerical analysis is.
Preparing Your Reporting Environment
Setting up the right foundation ensures the QWeb engine works smoothly and avoids errors during rendering.
Activating Developer Mode for Technical Reporting
Developer mode unlocks access to Technical settings. You will find menus for Reports, Actions and Views. This enables Odoo Developer mode reporting customization and simplifies copy, clone or extend actions.
Setting Up ir.actions.report Configuration
Every report in Odoo is connected with ir.actions.report. This object defines the template, paper format, model and report type.
Creating Custom Report Action XML
Below is an example of a basic XML configuration for registering a custom QWeb report.
Custom PDF Report
sale.order
qweb-pdf
module_name.custom_qweb_template
This configuration links your model with a new report option available for download and printing.
Building Custom QWeb Reports
Customizing QWeb reports requires knowledge of template blocks, loops and data binding.
Designing the Base QWeb Template in Odoo 19
QWeb template in Odoo 19 is built using XML. A basic structure includes t t-foreach for loops and t t-esc for fields.
<t t-name="module_name.custom_qweb_template">
<t t-call="web.external_layout">
<div class="page">
<h2 t-esc="doc.name"/>
</div>
</t>
</t>Using Conditional Logic and Loops in QWeb Templates
Conditional logic improves dynamic presentation of values.
<t t-if="doc.amount_total > 0">
<span>Total Amount Valid</span>
</t>
<t t-foreach="doc.order_line" t-as="line">
<tr>
<td t-esc="line.product_id.name"/>
<td t-esc="line.price_unit"/>
</tr>
</t></code></pre>Report Layout Inheritance and Template Extension
Template inheritance allows reuse of components. You can extend layout templates to maintain consistent branding across documents.
Adding Dynamic Report Data Using Odoo Model Fields
Model fields bind directly to report content. With Odoo model fields, technical consultants automate data rendering without hardcoding values.
Header and Footer Customization for Odoo Reports
Headers and footers support logos, page numbers and company details. These elements improve user friendly report design and enhance brand consistency.
Generating PDF and HTML Reports
PDF Report Generation in Odoo 19
Odoo internally uses wkhtmltopdf to produce accurate PDF report generation. By defining qweb pdf type in report settings, a printable document is generated instantly.
Exporting Reports to HTML or Printable Formats
Technical users can also enable HTML views for browser printing. This helps when quick previews are needed without downloading PDFs.
Creating Spreadsheet Reports in Odoo 19
Spreadsheet reports support multiple sheets and styling using Python logic.
Odoo 19 Spreadsheet and XLSX Report Creation
Developers create spreadsheet reports via XLSXWriter or built in Odoo spreadsheet models. Report XLSX export is used for financial analytics, budget comparisons and operational data.
Exporting Data to Excel for Accounting and Financial Reports
These exports are widely used for accountant or financial statements report customization. Data is mapped using Python code and then written to Excel rows and columns.
Best Practices for Technical Report Development
Data Cleaning and Archiving Before Report Generation
Clean data ensures accurate reporting. Removing duplicates and archiving old entries improves performance when generating large reports.
Ensuring User Friendly Report Design with Branding
Consistent branding builds trust. Always define company colors, logo placement and external layout templates for better readability.
