Spreadsheet-ready
Data and spreadsheet prep tools
Use this collection when the real job is not just converting a format, but getting messy data into a shape that a spreadsheet, import system, teammate, or client can trust.
Step 1
Diagnose CSV import failures
Start with delimiter, encoding, row-shape, missing-value, and column-profile signals before exporting to XLSX or uploading to a destination system.
Step 2
Clean table structure
Normalize headers, trim columns, remove duplicate rows, split or merge files, and keep the original data available for review before final import.
Step 3
Shape JSON into tables
Validate JSON, inspect key paths, flatten nested structures, and choose CSV or XLSX output only after the row shape is clear.
Step 4
Export and review workbook handoffs
Create XLSX outputs from clean CSV or JSON, convert simple XLSX sheets back to CSV when needed, and use schema tools to document expected fields.
