## ImportParser

<GenerationInfo sourceFile="packages/core/src/data-import/providers/import-parser/import-parser.ts" sourceLine="158" packageName="@vendure/core" />

Validates and parses CSV files into a data structure which can then be used to created new entities.
This is used internally by the [Importer](/current/core/reference/typescript-api/import-export/importer#importer).

```ts title="Signature"
class ImportParser {
    parseProducts(input: string | Stream, mainLanguage: LanguageCode = this.configService.defaultLanguageCode) => Promise<ParseResult<ParsedProductWithVariants>>;
}
```

<div className="members-wrapper">

### parseProducts

\<MemberInfo kind="method" type={`(input: string | Stream, mainLanguage: <a href='/current/core/reference/typescript-api/common/language-code#languagecode'>LanguageCode</a> = this.configService.defaultLanguageCode) => Promise<<a href='/current/core/reference/typescript-api/import-export/import-parser#parseresult'>ParseResult</a><<a href='/current/core/reference/typescript-api/import-export/import-parser#parsedproductwithvariants'>ParsedProductWithVariants</a>>>`}   />

Parses the contents of the [product import CSV file](/current/core/developer-guide/importing-data/#product-import-format) and
returns a data structure which can then be used to populate Vendure using the [FastImporterService](/current/core/reference/typescript-api/import-export/fast-importer-service#fastimporterservice).

## ParsedOptionGroup

<GenerationInfo sourceFile="packages/core/src/data-import/providers/import-parser/import-parser.ts" sourceLine="45" packageName="@vendure/core" />

The intermediate representation of an OptionGroup after it has been parsed
by the [ImportParser](/current/core/reference/typescript-api/import-export/import-parser#importparser).

```ts title="Signature"
interface ParsedOptionGroup {
    code?: string;
    translations: Array<{
        languageCode: LanguageCode;
        name: string;
        values: string[];
    }>;
}
```

<div className="members-wrapper">

### code

\<MemberInfo kind="property" type={`string`}   />

An optional explicit code for the option group, parsed from the CSV `name:code` syntax.
When two products specify the same code, they will share the option group.

### translations

\<MemberInfo kind="property" type={`Array<{         languageCode: <a href='/current/core/reference/typescript-api/common/language-code#languagecode'>LanguageCode</a>;         name: string;         values: string[];     }>`}   />

<GenerationInfo sourceFile="packages/core/src/data-import/providers/import-parser/import-parser.ts" sourceLine="67" packageName="@vendure/core" />

The intermediate representation of a Facet after it has been parsed
by the [ImportParser](/current/core/reference/typescript-api/import-export/import-parser#importparser).

## ParsedProductVariant

<GenerationInfo sourceFile="packages/core/src/data-import/providers/import-parser/import-parser.ts" sourceLine="83" packageName="@vendure/core" />
