Bulk product upload services for controlled batch imports

High-volume catalog imports require more than one-by-one product entry. Each batch needs a defined source file, destination template, field map, validation rules, acceptance checks, and an exception log. We prepare approved records for the import method available in your account, test a representative batch, resolve rejected rows, and report what was published, corrected, or returned for review.

Why brands trust Acelerar for bulk uploads

Multi-Platform Expertise

We handle bulk uploads for Amazon Seller Central, Shopify, WooCommerce, Magento, BigCommerce, eBay, Walmart, and custom platforms. Our team knows the exact template format, required fields, and validation rules for each platform.

Data Mapping & Transformation

Your product data rarely matches the platform’s required format. We map your source data to the target platform’s template, handle unit conversions, reformat descriptions, split variants, and fill in missing required fields.

Validation & Error Resolution

Bulk uploads fail when a single row has invalid data. We validate every row before upload, catch format errors, missing required fields, invalid category codes, and character limit violations. Failed rows are fixed and resubmitted, not ignored.

Image Processing & Upload

Bulk product uploads often require images to be hosted at specific URLs, meet size requirements, and follow naming conventions. We handle image resizing, format conversion, hosting, and URL mapping as part of the upload process.

Variant & Option Handling

Products with sizes, colors, materials, or other variations require specific parent-child relationships in bulk files. We configure variation groups correctly so all variants display properly and inventory tracks independently.

Scale Without Quality Loss

Large catalogs are divided into reviewable batches with the same approved field map, validation rules, and acceptance checks. Rejected rows and unresolved source-data issues are recorded instead of being hidden or guessed.

From raw data to live listings in 4 steps

1

Receive

You send us your product data in any format: spreadsheets, PDFs, supplier feeds, or existing platform exports. We assess the data quality and identify what needs mapping, cleaning, or enrichment.

2

Map

We transform your data into the target platform’s required format: field mapping, category assignment, variant structuring, image URL generation, and missing field completion.

3

Validate

Every row is validated against the platform’s rules before upload. Format errors, missing required fields, invalid values, and character limit violations are caught and fixed in advance.

4

Upload

Products are uploaded via CSV, API, or the platform’s bulk tools. We monitor the import, resolve any rejected items, and verify that all listings are live and displaying correctly.

Our teams are trained on the platforms you already use.
