Frequently Asked Questions

Is my data secure?

Yes. ToolXero processes all files locally on your computer. Your CSV data is never uploaded to any server or stored in the cloud.

What format of CSV is supported?

We support standard comma-separated values (CSV). For robust features like TSV, you can adjust delimiters manually in raw output if needed.

Can I convert large files?

Since processing is done on your machine, file size limits depend on your browser's memory. We typically handle files up to 50MB with ease.

How does 'Auto-detect' work?

It intelligently scans columns to identify numbers, booleans (true/false), and null values, mapping them to correct JSON types instead of just parsing everything as strings.
