Document Parsing and Chunking for Marketing Content in the

What Data for This Category Looks Like

Financial institutions use cultural and recreational goods data for customer marketing. This data mainly comes from brand product SKU lists, promotional activity rule documents, product detail page text exported from e-commerce platforms, cooperative authorization documents, and electronic versions of offline event materials. Updates do not follow a fixed schedule. They occur when new products launch, promotional plans are adjusted, or cooperative relationships change. Document types include structured Excel spreadsheets, unstructured Word documents, and PDF manuals. Fields cover product item numbers, materials, specifications, selling prices, inventory quantities, marketing copy text, and more. Units are mostly physical measurement units such as pieces, sets, boxes, and sheets. Some marketing documents include date fields for activity validity periods.

Constraints Imposed on Document Parsing and Chunking by These Characteristics

Structured SKU spreadsheets contain multiple specification entries for the same category. Parsing processes must avoid splitting the complete attribute combination of a single SKU. Unstructured marketing copy and activity documents contain contextual spoken expressions. Chunking processes must retain the semantic connection between adjacent paragraphs. Date fields in promotional documents are strongly bound to corresponding activity rules. Chunking processes must not break this logical connection. When multiple types of documents are uploaded together, parsing systems must adapt rules for Excel, Word, and PDF to avoid field misalignment or text truncation. Frequently updated marketing materials also require parsing processes to quickly adapt to new document formats.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`PARSE_FILE_MAX_SIZE`	`500 MB`	Marketing documents for cultural and recreational goods often include PDFs with high-resolution product images or Excel files with multiple sheets. This setting supports parsing of large file uploads.
`chunk_size`	`800–1200 characters`	Marketing copy and SKU information for cultural and recreational goods have moderate single-item length. 800–1200 characters preserves the semantic integrity of a single SKU group or complete activity paragraph.
`chunk_overlap`	`150–200 characters`	Marketing activity rules spanning chunks require retained contextual connection to avoid semantic breaks.
`EXCEL_PARSE_HEADER_ROW`	`Row 1`	The header of cultural and recreational goods SKU spreadsheets is usually located in the first row, containing core fields such as item number, product name, and specifications.
`PARSE_TIMEOUT_SECONDS`	`300 seconds`	Parsing Excel files with multiple sheets or PDFs with complex layouts requires longer processing time, to avoid timeout interruptions.
`AUTO_PARSE_MIXED_DOCS`	`Enabled`	Marketing materials often mix Excel, Word, and PDF formats. Automatic adaptation reduces manual configuration costs.

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. Testing on local samples is recommended before finalizing settings.

Three Common Mistakes

Issue: Field misalignment or partial SKU information loss occurs after uploading a SKU Excel file. Cause: The EXCEL_PARSE_HEADER_ROW parameter is not configured correctly, and a non-header row is recognized as the field identifier.
Issue: Semantic breaks appear in the chunking results of marketing copy documents, making it impossible to associate adjacent activity rules and discount descriptions. Cause: The chunk_overlap value is too low, and insufficient contextual connection characters are retained.
Issue: Parsing times out and fails after uploading a product instruction manual PDF. Cause: The PARSE_TIMEOUT_SECONDS value is not adjusted to accommodate documents with complex layouts, leading to forced termination of the parsing process.

How to Verify Proper Configuration

Upload a single SKU Excel test file, check that parsed fields match the original document, and adjust EXCEL_PARSE_HEADER_ROW to match the header position.
Upload a complete marketing activity document, confirm that the chunking results retain the contextual connection between activity rules and corresponding discount descriptions, and adjust chunk_overlap to the required length.
Upload a single-page product instruction manual PDF, check that the parsed text is complete, and adjust PARSE_TIMEOUT_SECONDS and PARSE_FILE_MAX_SIZE to accommodate the document size.
Upload marketing materials in mixed Excel, Word, and PDF formats, confirm that automatic parsing completes normally, and verify that AUTO_PARSE_MIXED_DOCS is enabled.
