JSON Record Collections to XLSX
Export JSON objects or arrays to a styled XLSX workbook. Root records appear in Data; nested property objects and arrays become Sheet2, Sheet3, and so on, in traversal order. Objects inside arrays form rows. @SheetN marks a child sheet; JSON Pointer identifies its source location. Property headers use key: to avoid metadata collisions. All cells are text: original numeric spelling is preserved, null is written as null, and missing properties are blank. Empty containers still have a header sheet. This is a table export, not a reversible JSON type encoding.

Document parsing & data extraction pipeline
Parses common comma- or tab-delimited text with quoted cells, embedded separators, multiline values, and doubled quote marks. Local tools can transpose or reorder CSV data, create SQL text, and generate a basic XLSX worksheet with fitted column widths and an autofilter. The parser is permissive rather than a strict RFC 4180 validator; the XLSX output does not add styling, frozen rows, typed-value inference, or a general mojibake repair guarantee.
Worked document extraction example
Scenario: Execute JSON Record Collections to XLSX with sample data to verify transformation accuracy and output formatting.
Sample input:
Processing: After the page loads, processing runs locally in a Worker without uploading the file. Cancel or clear stops the task.

File size & structure constraints
UTF-8 JSON must be smaller than 15,000,000 bytes. Limits: 256 sheets, 1,000,000 expanded cells across sheets, 16,384 columns, 1,048,576 rows per sheet, 64 MiB CSV output or 128 MiB XLSX output, and 30 seconds including file reading. ODS also has the shared 100,000 ZIP-entry, 16 MiB XML, XML depth 128 and 1,000,000-node limits. JSON nesting can create at most 64 child-sheet levels; each XLSX cell is limited to 32,767 UTF-16 units. Encrypted ODS and XML DTDs are rejected. XLSX uses blue bold headers, a frozen header row, filters and estimated column widths between 10 and 60. Widths are estimates from text length, not native font measurements. Each preview page has 16,000 characters; downloads contain the full output. Source sheet names, JSON keys and technical markers are not translated. Native Excel / LibreOffice compatibility is not certified.
JSON Record Collections to XLSX parses structured OpenXML and PDF data locally. Review exported tables or sheets against original files.
Zero-upload document security boundary
File buffers and document assets in JSON Record Collections to XLSX are processed in-memory via local browser APIs with zero file uploads to CZOA servers.
Document schemas & interchange standards
ECMA-376 Office Open XML specifications and ISO 32000 PDF reference standards:
- RFC 8259 (The JavaScript Object Notation Data Interchange Format)
