Frequently asked questions

What does "client-side" mean for Excel to Jira Table conversion?
"Client-side" means the entire Excel parsing pipeline runs inside your web browser, not on a remote server. Your Excel data is read from local memory, transformed into Jira Table format, and made available for download, without a single byte crossing a network.
How does the client-side Excel to Jira Table parser handle large files?
The parser runs inside a background Web Worker thread so the main UI thread stays responsive. Large Excel inputs are processed in streaming chunks when possible, keeping memory usage predictable even for multi-megabyte files.
Does client-side Excel to Jira Table conversion require any plugins or software installs?
No installation is required. The conversion runs inside your existing browser using standard JavaScript APIs. There are no browser extensions, desktop apps, or runtime plugins to install for client-side Excel to Jira Table processing.
Can I automate client-side Excel to Jira Table conversion in a CI/CD pipeline?
The web-based tool is designed for interactive, browser-based use. For fully automated pipeline use you would need a Node.js script. However, for ad-hoc or human-in-the-loop workflows, the client-side approach is the most private and friction-free option available.
Which browsers support the client-side Excel to Jira Table tool?
The tool is tested and fully supported in Chrome, Edge, Firefox, and Safari (latest two major versions). It relies on the File API, Blob, and Web Workers, all widely available. A Chromium-based browser is recommended for the best performance with heavy Excel files.
