How EDocGen Document Generator Works

From template to finished document in three steps — no coding, no manual formatting, no limits on volume.

TL;DR: EDocGen merges any data source into any document template to produce PDF, Word, PowerPoint, or Excel output — on-demand, in batch, or via API. You bring the template. You connect the data. EDocGen does the rest.

Step-by-Step: How Document Generation Works

Follow the four steps below to go from an existing template to an automatically generated, distributed document.

STEP 1

What is a document template — and how do you build one?

A document template is your existing Word, PDF, PowerPoint, or Excel file with dynamic field tags added wherever live data should appear. EDocGen uses a straightforward tag syntax:

// Text field
{{CustomerName}} — Dear {{CustomerName}}, your order total is {{OrderTotal}}.

// Repeating table row (loop over line items)
{{#each LineItems}}
  {{ProductName}}   {{Qty}}   {{UnitPrice}}
{{/each}}

// Conditional section
{{#if Discount}} Special discount applied: {{Discount}}% {{/if}}

You never need to redesign your templates. Add tags in Microsoft Word, then upload. The EDocGen template builder and Word add-in guide you through the process.

STEP 2

What data sources can you connect?

EDocGen connects to virtually every data source your business uses — no middleware required. Choose the source that fits your workflow:

📁 File-Based Sources

JSON XML Excel / XLSX CSV

🗄️ Relational Databases

SQL Server Oracle MySQL PostgreSQL MongoDB Azure SQL

☁️ Enterprise Applications

STEP 3

How is the document generated — and in what mode?

EDocGen supports three generation modes depending on your use case:

On-Demand

A user triggers a single document from a web form or button click. Completed document is returned immediately.

📦
Batch

Upload a bulk data file or run a database query to generate thousands of documents in one job. Results delivered as a ZIP or to cloud storage.

🔌
API / Automated

Trigger generation from any application via REST API. Integrate directly into your CRM, ERP, or workflow engine.

Here is a minimal API call to generate a document:

// POST /api/v1/document/generate
curl -X POST "https://api.edocgen.com/v1/document/generate" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "templateId": "invoice-template-001",
    "outputFormat": "pdf",
    "data": {
      "CustomerName": "Acme Corp",
      "OrderTotal": "$4,250.00",
      "LineItems": [
        { "ProductName": "EDocGen Pro", "Qty": 1, "UnitPrice": "$4,250" }
      ]
    }
  }'

STEP 4

What output formats does EDocGen produce?

Every generation job produces a finished, ready-to-use document in your chosen format:

Format Use Case Variants
PDF Invoices, contracts, reports, compliance documents Fillable (editable) · Flattened (locked) · Print-ready PCL5/PostScript
Word DOCX Letters, proposals, agreements, onboarding packs Standard DOCX · Editable after generation
PowerPoint PPTX Sales decks, board reports, property presentations Single slide · Multi-slide from data arrays
Excel XLSX Financial reports, data exports, bulk statements Single sheet · Multi-sheet · Formulas preserved
EDocGen supported template and output formats: PDF, Word, PowerPoint, Excel

Beyond Basic Mail Merge: What EDocGen Can Do Inside a Template

These capabilities are what separate document generation from a simple find-and-replace. Each is configured directly inside your template — no code required.

Conditional logic in document templates

Conditional Logic (IF-ELSE)

Show or hide entire sections, paragraphs, or table rows based on data values. Build one template that serves multiple scenarios.

How to use IF-ELSE →
Dynamic loops and repeating table rows

Loops & Repeating Tables

Automatically repeat table rows, list items, or document sections for every record in an array. No fixed row limits.

How to use loops →
Dynamic charts and graphs in Word and PDF

Dynamic Charts & Graphs

Auto-generate bar, pie, line, and area charts from live data. Chart data is passed at generation time — no manual updates needed.

How to add charts →
Dynamic image population in PDF and Word templates

Image Population

Insert logos, photos, or signatures dynamically from a URL, uploaded file, or Base64 string. Every document gets the right image automatically.

How to add images →
Arithmetic calculations inside document templates

Arithmetic Calculations

Compute totals, tax, discounts, and averages directly inside the template at generation time. Perfect for invoices and financial statements.

QR Codes & Barcodes

Embed dynamically generated QR codes and barcodes into any document. Ideal for tracking numbers, product labels, and invoice validation.

How to add QR codes →
Dynamic content blocks and sub-templates

Content Blocks & Sub-Templates

Conditionally inject entire paragraphs or embedded sub-templates into documents. Build modular, reusable document components.

How to use content blocks →
Multi-lingual document generation

Multi-Lingual Output

Generate the same document in multiple languages from a single template run. Supports Unicode, RTL languages, and locale-specific formatting.

Multi-lingual guide →
Document distribution via email, eSign and cloud

Automated Distribution

Deliver generated documents via email, eSign provider, or cloud storage in the same job. No manual download and send required.

Distribution options →
Document approval workflow automation

Approval Workflows

Route generated documents through one or more approvers before final delivery. Configure email notifications and approval actions.

Workflow setup →
Auto-generated digital forms from Word and PDF templates

Auto-Generated Web Forms

EDocGen converts any template into a fillable web form automatically. Share the URL with customers or staff — submission triggers document generation.

Frequently Asked Questions

Everything buyers, developers, and IT teams ask before getting started.

How does document generation work?
Document generation works by merging live data into a pre-built template to produce a completed document automatically. The three steps are: (1) create a template with dynamic merge field tags, (2) connect a data source such as a database, JSON file, CRM, or web form, and (3) trigger generation to produce the output. EDocGen handles all three steps without requiring any coding from business users.
What is the difference between document generation and mail merge?
Mail merge is a basic one-to-one text substitution inside Microsoft Word, limited to simple field replacement. Document generation supports conditional logic (IF-ELSE), nested loops for repeating data, dynamic charts, image population, calculated fields, multi-format output (PDF, PPTX, Excel), direct database connectivity, API-triggered automation, and omnichannel delivery — all without writing code.
Does EDocGen work without coding?
Yes. Business users can upload existing Word, PDF, PowerPoint, or Excel templates and connect data sources through a point-and-click interface. No programming is required for standard workflows. Developers who want deeper integration can use EDocGen's REST API with Python, C#, PHP, or Java SDKs.
Can EDocGen generate 10,000 documents at once?
Yes. EDocGen is designed for high-volume batch generation and can produce tens of thousands of documents in a single run from a database query or bulk data file. The platform is hosted on Google Cloud Platform and scales automatically to handle enterprise workloads.
Can EDocGen generate documents directly from a database?
Yes. EDocGen connects to SQL Server, Oracle, MySQL, PostgreSQL, and MongoDB. You provide a connection string and SQL query, map the result columns to your template's field tags, and generate documents in bulk. These configurations can be saved for one-click re-generation on a schedule.
Is EDocGen an API or a web application?
Both. EDocGen provides a web application for business users who prefer a no-code interface, and a REST API for developers who need to integrate document generation into their own applications, CRMs, ERPs, or workflow engines. Both modes share the same template library and data connectors.
Does EDocGen support conditional logic in templates?
Yes. EDocGen supports IF-ELSE conditional logic directly in templates. You can show or hide entire paragraphs, sections, table rows, or content blocks based on any data value — without writing any code. Conditions can be nested and combined with AND/OR operators.
How secure is EDocGen?
EDocGen is hosted on Google Cloud Platform with AES-256 encryption at rest and in transit. All uploaded data files are automatically deleted after document generation completes. A HIPAA Business Associate Agreement (BAA) is available for healthcare customers, and a Data Protection Addendum (DPA) is available for GDPR compliance.
