Frequently Asked Questions

What is the maximum text or data size I can process?

Because ToolFlare executes entirely inside your local browser memory, there are no artificial server-side limits. However, for the best performance and to prevent browser tab crashes, we recommend keeping input sizes under 5MB at a time.

What formats are supported?

This tool natively accepts standard UTF-8 text encoding. Please ensure your input string or configuration aligns with official standard specifications to prevent parsing failures.

How do I resolve common errors?

Common errors typically occur from malformed syntax, such as trailing commas, unescaped characters, or missing quotes. Our client-side processor will display the exact error trace if your input fails to compile, helping you quickly identify the problem.
