Configure 1C to CSV conversion

1C processing needs saved structure, field types and export rules. That is why it runs in the account, not in the quick site converter.

01 Add a data source

Upload a file or connect a recurring source.

02 Configure output structure

Choose fields, column or node order, nested-data rules and filters.

03 Save the profile

Check the preview and reuse the profile manually, on schedule or with delivery.

Need transformations, not just format conversion?

Sign up when you need to change values in cells, resize and convert images, or filter exports to include only selected items.

Increase prices for a supplier or product group by 7% and round them. Build a product name from SKU, manufacturer, model and attributes Convert images to JPG/PNG/WebP, resize them and add a watermark Schedule automatic transformations and deliver the result to the right channel.

format guide

What is a 1C to CSV converter

A 1C to CSV converter reads data in one format and builds output in another structure. It is useful when a supplier, CMS, ERP, marketplace or internal system expects a different file from the one you have. For simple files Eofferix can move fields automatically. In production workflows, rules matter: which fields are kept, how columns or tags are named, how nested data is handled, how empty values are normalized and which records are excluded.

When you need it

When data exists in one format but the next system expects another format or structure.

What Eofferix does

The service reads the source, detects repeated records and builds output with clear fields.

Why rules matter

The same file can be exported as a flat table, XML nodes, JSON structure or a feed.

example

1C to CSV example

This simple example shows the basic conversion. After signup, fields, filters, order and recurring runs can be configured.

Before

Код=SKU-001
Наименование=iPhone 15
Цена=999
Остаток=12

Код=SKU-002
Наименование=Samsung S24
Цена=899
Остаток=8

After

CSV

Category	Images	Name	Price	SKU	Stock
Smartphones	["front.jpg","back.jpg"]	iPhone 15	999	SKU-001	12
Smartphones	["s24.jpg"]	Samsung S24	899	SKU-002	8

A profile can save mapping, filters, value transformations and result delivery.

After signup and profile setup

use cases

When you need a 1C to CSV converter

These conversions are commonly used for catalogs, price lists, stock data, partner exchange and files prepared for receiving-system requirements.

Supplier catalogs

Bring supplier files to the structure expected by a site, CMS, ERP or PIM.

Price lists and stock

Prepare prices, availability, SKUs and categories for import or checks.

Marketplaces and channels

Build files for channel requirements, required fields and stable IDs.

Internal integrations

Move data between systems that use different exchange formats.

Manual review

Get a readable structure for managers, analysts or content teams.

Recurring exports

Run the same scenario repeatedly without manual setup.

common errors

Common 1C to CSV conversion mistakes

Errors usually come from nesting, mixed value types, empty fields and receiver requirements.

Repeated node not selected

Define which records become rows, objects, nodes or offers.

Lost nesting

Arrays and nested objects need a rule: keep, split or move separately.

Different fields

If records have different fields, decide how empty values are handled.

Types not normalized

Prices, dates, true/false and HTML should be normalized.

No filters

Without filters, inactive products or extra categories may be exported.

No validation

Before recurring runs, check preview, encoding and required fields.

comparison

1C to CSV online or manual conversion

A one-time check and production exchange need different approaches.

Method	Pros	Cons
Manual code	Maximum flexibility for unique schemas.	Requires developer time, tests and maintenance.
Script	Fast for repeated technical tasks.	Harder to control files, logs, permissions, schedule and delivery.
Eofferix	Preview, profiles, rules, files up to 2 GB and scheduled runs.	Complex structures need a saved profile.

limits and safety

Limits, safety and recurring workflows

Eofferix creates a separate output and does not change the source file. For large catalogs and exact rules, use a saved profile.

Up to 5 MB without signup

Good for quick checks of simple files.

Up to 2 GB after signup

Large catalogs are processed in the account with saved rules.

Source stays unchanged

Output is created as a separate file.

Structure control

When supplier data changes, update only affected rules.

Value transformations

Normalize text, prices, empty values and fields.

Result delivery

Email, FTP/SFTP, webhook and other channels for repeat processes.
