  • `it is json file` a) you can find a tag that more precisely characterises your question than [tag:file]: [tag:json] b) you can *edit* your post - putting essential information like `find the line by searching the id and change the size` should *not* go in a comment. c) what *is* your [specific programming problem](https://stackoverflow.com/help/on-topic)? Figuring out the `ID` to find? Finding it in all those data sets? Manipulating `Size` in records found? Having the new value cause some specific effect? – greybeard Feb 19 '19 at 23:58
