Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
We are reading big xlsx file (~60k cells and 6mb). process.memoryUsage shows:
After that we need to parse it as a json using XLSX.utils.sheet_to_json().
process.memoryUsage() now shows:
Idle process - something like 100 mb memory.
Is there any way to parse it partially?
@KindOf You aren't the only one to notice the problem! After looking into https://github.com/SheetJS/js-xlsx/issues/764 it seems to be a nodejs issue: https://github.com/nodejs/node/issues/14652
Can you try reverting back to node 4.x? See the triage of the issue
