CSV with value of "NA" read as empty string

[alexp8]

I have a simple CSV:

header1,header2,header3 aa,bb,cc dd,ee,ff gg,NA,ii

Using Table.read().csv(), will remove "NA" from the csv.

Is this a known issue?

Hi @alexp8. This is not an issue: by default "NA" is considered a missing value indicator when reading files, along with a few others textual values ("N/A", "NaN", etc.).

You can set the list of missing value indicators to you liking by using the missingValueIndicator(String...) method of CsvReadOptions and use these options to read the file.

Edit for clarity: this is done through the CsvReadOptions.Builder, not CsvReadOptions directly

I see, thanks so much!
