What file merging means
File merging brings data from several sources into one model: consistent fields, unified column names, duplicate rules and one output for catalog, price-list or import workflows.
When you need it
When manual file editing becomes slow and error-prone.
What Eofferix does
The service saves processing rules and applies them to repeat files.
Why profile matters
A profile keeps output structure, filters, mapping and delivery.
File merge example
The example shows the basic output logic. A profile can add more rules and checks.
Before
supplier files| file | sku | name | price | stock |
|---|---|---|---|---|
| supplier_a.csv | SKU-001 | iPhone 15 | 999 | |
| supplier_b.xlsx | SKU-001 | iPhone 15 | 12 | |
| supplier_b.xlsx | SKU-002 | Samsung S24 | 8 |
After
unified catalog| sku | name | price | stock | source |
|---|---|---|---|---|
| SKU-001 | iPhone 15 | 999 | 12 | supplier_a + supplier_b |
| SKU-002 | Samsung S24 | 8 | supplier_b |
When you need file merging
The tool is useful for catalogs, price lists, stock data and recurring supplier files.
Supplier catalogs
Bring different structures to one model.
Price lists
Normalize prices, names and SKUs.
Stock data
Filter and update product availability.
CMS/ERP import
Prepare files for receiver requirements.
Quality control
Check output before recurring runs.
Recurring workflows
Repeat processing without manual setup.
Common workflow setup mistakes
Problems appear when field, filter, duplicate and value-type rules are not defined upfront.
No unified model
Different sources need field rules.
Duplicates not defined
One product can arrive from several files.
No filters
Extra rows reach output.
Types not normalized
Prices, dates and active flags are read differently.
No preview
Errors are noticed only after import.
No rule version
Source changes become harder to diagnose.
Eofferix or manual processing
Manual work fits one file. Repeat workflows are better handled with saved rules.
| Method | Pros | Cons |
|---|---|---|
| Manual editing | Fast for one file. | Error-prone and hard to repeat. |
| Script | Flexible for technical teams. | Needs maintenance, logs and error handling. |
| Eofferix | Profiles, preview, rules, large files and schedule. | Workflow needs initial setup. |
