FAQ/ Error Message oudan.csv file format is invalid

We are trying to import regular river crossing data.

[Import river crossing data] When I selected , I got the following error:

oudan.csv: 1: Invalid file format.

How do I fix oudan.csv?


  • The first line of oudan.csv must contain 16 commas (,).
  • Set the correct values for columns A, G, and L.
  • Other column values are ignored. That is, there can be a character between the comma (,) and the comma, or a space.
  • If there are not enough commas, an error will occur.

  • Correct example

  • Incorrect example (no 15 commas)
