Have a folder of CSVs to convert? Drop them all - the converter processes each file independently, applies your conversion settings (delimiter, type inference, header handling) uniformly, and bundles the JSON outputs as a single downloadable ZIP. No upload, no signup, no per-file cap beyond browser memory.
When to use this
Use for: migrating a CSV-based data dump (one CSV per table / day / customer), converting batch report exports from analytics tools, bulk-prepping test fixtures, processing a folder of customer-feedback CSVs into JSON for downstream tooling.
Frequently Asked Questions
How many CSVs can I convert at once?
Practical limit is browser memory - most laptops handle 50-200 CSVs per batch, each up to ~10 MB. For very large batches (1000+), split into chunks. Each file is processed independently, so partial failures only affect the offending file.
Can I use different settings per file?
No - bulk mode applies the same delimiter / header / type settings to every file. If your CSVs have different formats, run them in separate batches with the right settings each time.
