Can you give an example of why you need that? Genuinely curious

Not convinced making it open source will increase their development speed.

This is very cool! I wish the IL acronym was explained in the text, though.

Guessing from the number (168), probably second year? So not too basic if that's what you're implying

Nevermind, the tab character is indeed what's needed to split it into multiple cells.

Re:Show HN: Extract Table from Image on Saturday October 02, 2021 @04:50PM (#28731961)

I've added support for urls now! Please try it.

Re:Show HN: Extract Table from Image on Saturday October 02, 2021 @04:20PM (#28731736)

Thanks! No, I hadn't heard of either - thank you!

Re:Show HN: Extract Table from Image on Saturday October 02, 2021 @04:20PM (#28731731)

Interesting, thanks!

Do you happen to know how to paste regular UTF-8 text into Excel/Google sheets as multiple cells? If I copy two cells in Sheets, I get a tab character (\t) between the cells. But if I try to paste "hello \t world" into Sheets then it's just dumped into one cell.

Re:Show HN: Extract Table from Image on Saturday October 02, 2021 @04:17PM (#28731709)

That's interesting. Thanks for reporting!

Re:Show HN: Extract Table from Image on Saturday October 02, 2021 @04:16PM (#28731697)

Thank you! I have also been kind of obsessed with this problem. I have tried to solve it myself, going from an image to bounding boxes and trying to separate the boxes into columns. But that problem is just fraught with edge cases, so I decided to just use an existing tool.

Re:Show HN: Extract Table from Image on Saturday October 02, 2021 @04:14PM (#28731673)

This currently returns an error if it doesn't find exactly one table in the image, so it might be able to work with larger images, but probably not if there are multiple distinct blocks of text.

Re:Show HN: Extract Table from Image on Saturday October 02, 2021 @04:12PM (#28731653)

Thanks! No, not that I know of, looks like for the AWS cli it needs to be in an S3 bucket, based on looking at this document: https://docs.aws.amazon.com/cli/latest/reference/textract/an...

Re:Show HN: Extract Table from Image on Wednesday September 29, 2021 @03:31PM (#28698699)

Directly, no preprocessing! The postprocessing is concatenating all words that belong to the same cell.
