Hi Kaleb
I was hoping if there is a tutorial link or sample step by step python code for updating/inserting/deleting rows in airtable iteratively as well as 1 time (similar to your code and tutorial for download)

Hi @sanky23 – thanks for your inquiry. You can preview a draft version of the step-by-step tutorial for uploading here at this link: https://medium.com/@kalebnyquist/airtable-python-made-possible-uploading-data-into-airtable-from-python-using-airtables-api-3075009abf98

Hopefully this is still helpful for you. Let me know what you think!

Thanks Kaleb
This is really helpful .I need help a bit even deeper looking at my case study.
I am comfortable now with updating/adding airtable record from python if we define json for new records or matching value hardcoded manually .

it will be really great if there are examples for say.1) if i have pandas dataframe of few rows which i have to insert into existing airtable table, based on matching condition on single or multiple columns or index of the dataframe ,2) another example of creating new table in airtable in existing base from pandas dataframe (struggling to convert dataframe into json required for airtable post request)

Thanks

@sanky23, it might not be quite the solution what you're looking for, but I've added a function upload_pandas_dataframe() to the gist above. See if you can get it to work for you. I'll try and incorporate your question in the final draft of the tutorial when it is published.

,2) another example of creating new table in airtable in existing base from pandas dataframe (struggling to convert dataframe into json required for airtable post request)

This question requires working with Airtable's metadata API, which is still in limited release and you will have to register for. Learn more here: airtable.com/api/meta

Hi @KalebNyquist , I found your script from your medium article Airtable & Python Made Possible: Downloading Airtable Data into Python using Airtable’s API. It is not directly hosted on medium but embedded on "towardsdatascience" website. I was thinking to create something like this but this is well done. Thanks for sharing.

@KalebNyquist awesome funs mate. thanks for making this available.
