Data export: Excel → CSV → JSON
Move spreadsheet data into formats for scripts, APIs, and imports.
Analysts and developers often receive Excel attachments but need CSV for databases or JSON for apps. This workflow stays local — customer lists never hit third-party formatters.

When to use this workflow
Use when you received an Excel attachment but need CSV for a database import, when developers need JSON from a spreadsheet export, or when compliance forbids uploading customer data to third-party formatters.
Tips for best results
Export UTF-8 CSV for international characters.
Open CSV in a text editor once to verify quoting before automated imports.
Keep the original xlsx as the source of truth — CSV is a transfer format.
Before you submit
- Column headers match target system field names
- No scientific notation on ID columns
- Dates formatted as expected by importer
- Sensitive file deleted from Downloads after use

Payroll and customer exports contain PII. Browser-local conversion avoids sending rows to random online tools.
