How EDocGen Document Generator Works

Q: What is the difference between document generation and mail merge?

Mail merge is a basic one-to-one text substitution in Microsoft Word. Document generation supports conditional logic, nested loops, dynamic charts, calculated fields, multi-format output (PDF, PPTX, Excel), direct database connectivity, API triggers, and omnichannel delivery — all without code.

Q: Does EDocGen work without coding?

Yes. Business users upload existing templates and connect data sources through a point-and-click interface. Developers can use EDocGen's REST API with Python, C#, PHP, or Java.

Q: Can EDocGen generate 10,000 documents at once?

Yes. EDocGen is designed for high-volume batch generation hosted on Google Cloud Platform and scales automatically for enterprise workloads.

Q: Is EDocGen an API or a web application?

Both. A web application for business users and a REST API for developers to integrate document generation into their own systems.

Q: Does EDocGen support conditional logic?

Yes. IF-ELSE conditional logic is supported directly in templates. Show or hide paragraphs, sections, or table rows based on any data value without writing code.

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 REST API. You bring the template and the data. EDocGen does the rest.

Step-by-Step: How Document Generation Works

Follow the four steps below to go from an existing file 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 merge tags added wherever live data should appear. EDocGen uses a straightforward tag syntax — no programming knowledge needed:

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

// Repeating table row (loop over an array)

{#TableName}

{ProductName} {Qty} {UnitPrice}

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

Your templates stay in their native format (Word, PDF, etc.). You never need to convert them. Add tags in Microsoft Word or PowerPoint Or Excel and upload directly in the system.

STEP 2

What data sources can you connect?

EDocGen connects to virtually every data source your business uses — no middleware required.

STEP 3

How is the document generated — and in which mode?

Three generation modes cover every business scenario:

⚡

On-Demand

A single user triggers one document from a web form or button click. Returned immediately.

📦

Batch

Upload a data file or run a database query to generate thousands of documents in one job.

🔌

API / Automated

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

Minimal API call example:

// 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-001",
    "outputFormat": "pdf",
    "data": {
      "CustomerName": "Acme Corp",
      "OrderTotal": "$4,250.00"
    }
  }'

STEP 4

What output formats does EDocGen produce?

Every generation job produces a finished document in your chosen format:

Format	Common Use Case	Variants
PDF	Invoices, contracts, compliance reports	Fillable · Flattened · PCL5 / PostScript
Word DOCX	Letters, proposals, onboarding packs	Editable after generation
PowerPoint PPTX	Sales decks, board reports, property presentations	Single slide · Multi-slide from arrays
Excel XLSX	Financial reports, bulk statements, data exports	Single sheet · Multi-sheet · Formulas preserved

EDocGen supported output formats: PDF, Word, PowerPoint, Excel

Beyond Basic Mail Merge: What EDocGen Does Inside a Template

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

Conditional Logic (IF-ELSE)

Show or hide sections, paragraphs, or rows based on data values. One template, multiple scenarios.

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 tags, (2) connect a data source such as a database, JSON file, CRM, or web form, and (3) trigger generation to produce the output document. EDocGen handles all three steps without requiring any coding.

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, nested loops for repeating data, dynamic charts, 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.

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 for 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. Conditions can be nested and combined with AND/OR operators — no code required.

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.
