User Guide: Parsing Excel sheets into clean structured JSON
What is Excel to JSON Parsing?
Excel tables organize data inside tabular grids. For software developers, this data must be parsed, cleaned, and exported as JSON list entities for database migrations or mock servers. This tool parses the Excel cell matrices dynamically inside your browser, mapping column headers to object keys.
Step-by-Step Instructions
- Upload File: Drag and drop your `.xlsx`, `.xls`, `.ods`, or `.csv` file into the upload dropzone.
- Set Configurations: Select which worksheet sheet tab to parse, set the header index line, and specify where rows start.
- Refine Output: Enable type auto-casting to ensure true booleans and numbers are rendered instead of plain text strings.
Nested Unflattening Support
Symmetrical to our Excel exporter, the importer reads column dot coordinates (like user.profile.name) and reconstructs nested JSON parent trees automatically. Cells with empty values are output as empty fields or ignored based on formatting preferences.
