About this Gig
Have nested JSON or an API response that will not fit cleanly into CSV or Excel?
I will transform complex objects and arrays into structured, analysis-ready rows and columns. You will receive a verified CSV or XLSX file with the fields organized exactly as required.
I can help with nested objects and arrays, API responses and exported data, custom column names and ordering, multiple JSON files, data cleaning and validation, and reusable Python converters.
Why work with me? I bring 10+ years of software development experience, 337 completed Fiverr orders, clear communication, and reliable delivery.
The Basic package is ideal for a simple file conversion. Choose Standard for nested JSON and custom columns, or Premium when you need a reusable Python script with documentation.
Please send a small sample JSON and your desired output structure before ordering complex, large, deeply nested, or sensitive-data projects. I will confirm the right package and approach.

FAQ
Can you flatten deeply nested JSON or API responses?
Yes. I can flatten nested objects and arrays into clean CSV or Excel columns. Please send a small sample so I can confirm the exact structure.
Will I receive only the converted file or also the Python script?
Basic includes the converted CSV or Excel output. Choose Premium, or add source code as an extra, if you need a reusable Python script.
What should I send before ordering?
Please send a sample JSON file, your desired CSV or Excel columns, and any rules for naming, filtering, merging, or cleaning the data.
Can you work with large JSON files?
Yes. I can work with large JSON files, but please message me first with the file size and a small sample so I can confirm the best approach and package.
Can you match a specific CSV or Excel format?
Yes. If you send an example output file or column list, I can structure the converted data to match your required CSV/XLSX format.

I sent a large file with complex requirements to several people, which I barely managed to articulate due to my limited knowledge of Python and coding in general. Only Serhii was able to understand my request. I was initially skeptical, but when the results came back, I realized his exceptional talent....
