I have 3 files that I am using to test this feature that are 100MB, 300MB, and 700MB in size. The 3 files have identical headers -- I created the 100MB and 300MB versions by deleting rows from the original 700MB test file. Despite that, though, I get an empty data field and the following error when trying to parse the 700MB version but not the other two:
{
"type": "Delimiter",
"code": "UndetectableDelimiter",
"message": "Unable to auto-detect delimiting character; defaulted to ','"
}
Specifying the delimiter and newline options when parsing does not get rid of this error. The error appears after a few seconds' delay, which surprised me anyway as I'm just trying to preview a single line. Would really appreciate any help or suggested workarounds here!

If you use the "streaming" setup it lets you handle much larger files.
Here is how it's normally used:
let results: string[][] = [];
Papa.parse(file, {
preview: 100000,
worker: true,
step: (result) => {
// Called on every chunk read from the file.
if (result.data) {
results.push(result.data);
}
},
complete: (test) => {
// Final results
console.log(results);
},
});
But since you're only reading one row you can simplify to this:
Papa.parse(file, {
preview: 1,
worker: true,
step: (result) => {
// First and only chunk
console.log(result.data);
},
});
I'm using the
preview
option when parsing to validate that the header row of a file matches a set of expected headers before attempting to upload:I have 3 files that I am using to test this feature that are 100MB, 300MB, and 700MB in size.
