Currently it fails when creating a worksheet:

panicked at library/std/src/sys/wasm/../unsupported/time.rs:31:9:
time not implemented on this platform

Replacing std::time::SystemTime with chrono will probably fix the problem as chrono works with web assembly.

Some questions:

  1. What version of rustc are you using?
  2. What version of rust_xlsxwriter are you using?
  3. What rust_xlsxwriter feature flags are you using?
  4. Are you using the rust_xlsxwriter wasm flag?
  5. What wasm compiler or compilation method are you using (node, browser, deno, wasmtime, other)?
  6. Could you try the example here: https://github.com/Clipi-12/rust_xlsx_wasm_example and let me know if it works?
  7. Could you post a minimal working example that demonstrates the issue.

All my apologies, I did not configure the wasm flag.

Work great with this flag !

Thank you.

Great. Just for the record what wasm method are you using?
