I will convert json to CSV or CSV to json with validation
About this Gig
Convert one JSON file to CSV for a spreadsheet, or one CSV file to JSON for an import. I use AgenteRendaAI with supervised validation before delivery.
You receive one UTF-8 output file plus a report with row count, column count and field names.
Example: CSV id,name with a row 001,Ana becomes JSON [{"id":"001","name":"Ana"}]. Leading zeros are preserved because CSV values remain strings in JSON.
Package: one file, one direction, up to 100KB, 1000 rows and 30 columns. Input must be a valid comma-delimited CSV with unique headers or a JSON array of flat objects. Missing/null JSON values become empty CSV cells. Quotes, commas, line breaks and Unicode are handled. Formula-like CSV cells receive a protective prefix for spreadsheet safety.
Includes one revision for conversion issues on the same input. No nested JSON, Excel workbooks, scraping, enrichment, API integration or malformed-file repair.
Provide non-sensitive data only. Specify JSON to CSV or CSV to JSON and your preferred column order. If unsure about compatibility, message me on Fiverr with a small non-sensitive sample before ordering.

FAQ
Do you use AI and what files are supported?
Yes, I use a supervised AI-assisted workflow and validate the output. This package supports valid CSV or flat JSON arrays only, up to 100KB, 1000 rows and 30 columns. CSV values stay strings to preserve identifiers and leading zeros.
