Or just do something like:
If you're fortunate enough to be able to put `data.csv` on the MySQL server, that is.
...or if you can use the LOAD DATA LOCAL INFILE syntax on that server/client.

In my experience, this is actually not that difficult or novel, but kudos on trying new things. Keep it up :)
Absolutely. I did come here to do the "so what" dance but this is the simplest and most respectful comment here.
Keep on making new (to you) things, keep a good log of what you have done (GitHub) - eventually you will make new (to anyone) things.

I'm surprised by how many things that aren't that difficult or novel end up on the front page. CSV related projects come to the fore every week.
Heh, maybe I should start submitting some of my more trivial projects and rack up the HN karma ;)
i.e. "A testing utility for database migrations"

I am not putting 1TB+ per table dumps of data into a strangers website what can be done with a bit of sed or a script in ${LANGUAGE}.
Loader from Several Nines, is a tool for doing parallel loads of CSV into MySQL and MariaDB https://github.com/severalnines/loader
Mydumper is a threaded dump and load tool for MySQL/MariaDB. https://launchpad.net/mydumper
Tungsten Replicate can do batch load replication into any external datasource http://docs.continuent.com/tungsten-replicator-3.0/deploymen... So long as you have a script for it: https://code.google.com/p/tungsten-replicator/source/browse/...

think it would be actually funny if you did, bogus data that is of course.
But uploading your files to some site that reformats plain text, this does not belong on hacker news imho.

MySQL already supports loading CSVs directly, why convert them first? http://dev.mysql.com/doc/refman/5.1/en/load-data.html
It also has the CSV storage engine which actually uses a CSV file as its data back-end, no conversion required.

There are occasions where you can't just do a straight insert. Perhaps you need to conditionally create a foreign record, or you want to format a value on insert instead of doing it directly in the CSV.
That said, I can't see how the OP actually helps me with that.

LOAD DATA INFILE can't conditionally create a foreign record, but you can certainly format a value on insert by using the SET clause, for example:
LOAD DATA INFILE 'people.txt'
INTO TABLE Person (@first, @last, date_of_birth)
SET full_name = CONCAT(LEFT(@first, 1), '. ', @last);
LOAD DATA INFILE 'projects.txt'
INTO TABLE Projects(@first, @last, project)
SET person_id =
(SELECT id FROM people
WHERE name = CONCAT(@first, ' ', @last) LIMIT 1);Cool! I wasn't aware you could do that sort of thing with LOAD DATA INFILE. Thanks :)
I didn't know that either - thanks for sharing.
Much more frequently I run into the issue that my csv isn't perfectly formed. Some people have funny ideas about how to handle newlines or escape quotes/commas.
Yeah.. I'd be interested in something that does the opposite of this tool actually. LOAD DATA INFILE is a lot faster than SQL query files for heavier data
This submits to your server. If I have sensitive data, I sure as hell don't want that going somewhere where it might be stored.
Why isn't this just done client-side in Javascript?

why isn't this a trivial bash script more like it.
Indeed, but that's already been done.
Because the author prefers to code in something else?
The first python script I ever wrote does csv to SQL: https://github.com/elidickinson/csv-tools/blob/master/csv2sq... It's very rough, but I actually still use it on occasion. The Python csv library is quite good. There's a lot that can go wrong that LOAD DATA can't handle.
I actually have some code (.Net) that loads xml, csv, ... into objects.
There is also a visual drawing to help you connect the dots between the properties of the uploaded file vs. the properties of the objects.
This way, all information gets loaded into the db from a single import, in the correct table.
I could seperate it in a opensource project i suppose, if anyone is interested.

I submitted the following file (note the blanks):
$ cat testblanks.csv
1997, Ford, E350
The following was returned: CREATE TABLE testblanks (Column_1 NUMERIC(32, 16),Column_2 VARCHAR(5) CHARACTER SET utf8,Column_3 VARCHAR(5) CHARACTER SET utf8); INSERT INTO testblanks VALUES (1997,' Ford',' E350');
That was in accordance with http://tools.ietf.org/html/rfc4180
Cool!
But the CSV format has a lot of "gotchas." See, for example, http://discuss.fogcreek.com/joelonsoftware3/default.asp?cmd=.... Especially the rant about the Microsoft version of CSV.

In the wild, CSV is less a format and more a meta-format (and a subset of the *SV family) with plenty of variability between dialects.

Nice idea.
Can I suggest another idea? Take JSON files, and convert them into MySQL, postgres etc insert/update scripts. There is a need for this. For example, I run this hobby site http://kivatools.com that imports tons of data from kiva.org - their data dumps are in json/xml format. so I've a script that refreshes the db every night, with a couple of gigs of data. It would be very useful if there was a service that can take a url (or file), and convert json/xml into mysql scripts.

I think it can be done in few lines of ruby/python/whatever code. Without submitting sensitive data to remote unknown server. IMHO it would be much better idea to release code as opensource.
You should be able to do this entire thing in-browser. Going further, leveraging WebSQL or SQL.js, it should be possible to pump the queries into a client-side database and run queries.

Tried it with a file containing this:
Field1,Field2,Field3,Int,Float,Quoted

This is great! People should have better and faster ways of handling CSV -> DB interactions. We recently added native CSV loading into blaze for MySQL, PostgreSQL, and SQLITE, https://github.com/ContinuumIO/blaze/blob/master/blaze/data/...
MongoDB is coming soon.

Here's one I made a few years ago:
http://utilitymill.com/utility/csv_to_create_table/
You just paste the content from excel or a csv.
It actually tries to figure out the data types and creates a table for you as well.

Tested it out with GeoIPCountryWhois.csv from Maxmind, seems to work ok. However selecting the output is almost impossible, locks up Chrome. This isn't your apps fault of course. Usually I use Sequel Pro for this, which allows me to map csv fields to db columns
I've found phpMyAdmin's CSV insert feature has been very useful.
Allows for quite a few options.

So does this work with CSV?
What is this for ridiculous product/ attempt?

Quite amusing, people down voting my 'minimal worded critique', apparently really like this tool and see a benefit that is non-existing. Apparently can't think beyond a solution to a problem.
Reformatting of ascii/text data, a csv, is not rocket science. Nor 'hacker (news) quality'.
And i hope that nobody afterwards realises that they should not have uploaded their csv file to your website hosted by nsa friendly google. Also adding a warning that people are submitting their data to (google, 3rd party servers you don't control) servers, would be nicer, and makes people perhaps aware that their data goes further then only their own browser.

you were not elegant or polite, but are in fact correct
