Frequently Asked Questions

Everything you need to know about converting JSON to Excel

Absolutely safe! JsonExport processes everything in your browser using JavaScript. Your data never leaves your computer - no uploads, no servers, 100% private.

Why Choose JsonExport for CSV Data

Opening raw CSV files directly in Microsoft Excel often causes data corruption: leading zeros are stripped from account numbers, dates are misinterpreted, and non-ASCII characters break. Converting CSV to native .xlsx before opening fixes these issues permanently.

Generates authentic binary .xlsx files (not renamed CSV text files)
Preserves leading zeros on ID codes, phone numbers, and zip codes
Maintains UTF-8 international character encoding flawlessly
100% private: Converts files locally in your browser memory

Frequently Asked Questions

Why not just open the CSV file in Excel directly?

Excel often strips leading zeros (turning "00123" into "123") and mutates date strings when opening raw CSVs. Generating a real .xlsx workbook preserves the exact string data.

Does this support TSV (Tab-Separated Values)?

Yes. Our engine detects tab delimiters automatically and creates structured columns accordingly.
