"2 billion records" : by record, you mean cells, like a sheet with 2048 columns and 1048576 rows ? By quickly looking at the code I can't see an obvious limitation, but that doesn't mean anything. Closer investigation would be needed. Please file an issue at https://github.com/OSGeo/gdal/issues/new with exact details how to reproduce (number of rows/features, and columns/fields in particular). But even if the writer side would work, the OGR reader side would probably have issues as the whole spreadsheet will be loaded into RAM and for 2 billion cells, I would expect at least 32 or more GB of RAM to be needed. Perhaps spreadsheet software are able to cope with that in a smarter way. Even Le 10/01/2022 à 11:27, Kopszak Marta - Partner Hurt a écrit : Dear Sirs, I ran into an error when exporting data through the OGR library to the .xlsx and .ods format. The bug occurs when there are more than 2 billion records in the database. I know the problem was solved for other formats, e.g. csv. Will the problem be solved also for other formats (e.g. xlsx, .ods)? If this is not the correct e-mail, please forward this e-mail to the appropriate person.
