Frequently Asked Questions

Common questions about TSV to XLSX conversion

How does in-browser TSV to XLSX conversion protect my privacy?

Unlike legacy file converters that upload your confidential files to cloud servers, OpenFileConverter runs 100% locally on your computer or phone using Rust WebAssembly. Your original TSV files never leave your device memory, guaranteeing zero retention.

What is the main difference between TSV and XLSX?

TSV (Tab-Separated Values) provides database imports, bioinformatics data, and tabular text without comma quote escaping, while XLSX (Microsoft Excel OpenXML Spreadsheet) is optimized for financial models, multi-sheet business analysis, pivot tables, and chart dashboards. Converting allows you to balance file size, compression fidelity, and platform compatibility.

Does converting TSV to XLSX degrade visual quality?

No. OpenFileConverter uses high-fidelity chroma subsampling with configurable quality levels (default 92%), ensuring virtually indistinguishable image fidelity with sharp edges and rich colors.

Can I convert multiple files in batch?

Yes. You can drag and drop up to 100 files simultaneously. Because processing executes in parallel on your local CPU threads, batch jobs finish in seconds without queue wait times.
